Syria is an active Conflict Zone. A civil war is ongoing since 2011. There is a high risk to civil aircraft. Syrian airspace (OSTT/Damascus FIR) should be avoided entirely. Airspace adjoining the Damascus FIR is also at risk: Cyprus, Turkey, Israel. Total flight ban for US, UK and German operators, and several other countries have issued warnings to avoid the airspace of Syria.

The primary risk is a misident by Syrian air defense systems. Civil aircraft may be targeted in error, or caught in crossfire during ongoing air attacks involving Israel, Russia, Iran. Missiles may erroneously lock on to civil aircraft. Israeli airstrikes on Syria are regular, and do not show any regard for civil traffic. There is a clear risk to civil aircraft operating on airways UL620, UW74, UR18, and UP62. In simple terms, if you find yourself planned overwater east of Cyprus, reconsider your route.

Major events:
June 2022: OSDI/Damascus airport closed for several days following Israeli airstrikes. Runways and terminal building both sustained damage.
Feb 2020: An A320 enroute OSDI/Damascus caught in crossfire during attack by 4 Israeli F-16’s, forced to divert to Russian controlled air base.
Sep 2018: Russian IL-20 shot down in error on FIR boundary with Cyprus (Nicosia FIR) - airline flights on UL620 within 50nm of this position.

Improving airspace risk picture in Yemen, where all parties in the ongoing conflict have agreed to extend a ceasefire to August 2. The first month of the ceasefire saw notably reduced hostilities; commercial flights resumed at OYSN/Sanaa Airport for the first in six years, and there were no reported drone strikes in Saudi Arabia.

However, Yemen remains an active conflict zone, and the vast majority of Yemeni airspace (OYSC/Sanaa FIR) should be avoided. The US, UK, France and Germany all prohibit aircraft from overflying any land portion of the FIR. US operators can still use UT702 and M999, while UK and German operators can use over water portions of N315, UL425 and R401 with limits as published by Notam (all well off the coast). Saudi Arabian airspace to the north and Somali airspace to the South also have risks.

The primary risk is intentional targeting by terrorist groups with access to sophisticated anti-aircraft weaponry. Civil aircraft may also be at danger from on-going high intensity military operations including the use of explosive drones and missiles. Saudi-led airstrikes can occur at any time with little regard to civil traffic, including in the capital Sana’a.
 
Major events:
June 2022: All parties in the Yemeni conflict have agreed to extend a ceasefire to August 2.
2018-2022: Frequent Saudi airstrikes on Sanaa and other targets in Yemen in retaliation for Houthi drone attacks across the border.
2017: OYSN/Sanaa Airport badly damaged by coalition airstrikes.

Ukraine closed its entire airspace to all civil traffic on Feb 24, 2022, due to a military invasion by Russia. There is an ongoing active conflict in Ukraine between Russian and Ukrainian forces. Russia, Belarus and Moldova have closed large sections of their own airspace near to their FIR boundaries with Ukraine.

All the major countries who regularly issue airspace warnings (the US, UK, Canada, France, Germany) have since issued total flight bans for Ukraine due to risk from military activity at all levels. (Several other countries have also issued flight bans for Ukraine but we have not listed them all here due to sheer volume).

The primary risk is an unintended targeting of civil aircraft by military, including misidentification (as with MAS17, UIA752), or confusion.

The secondary risk is potential lack of Ukrainian Air Traffic Control Service at short notice (Cyber Attack), and other unforeseeable non-normal operating environments for civil aircraft.

Prior to February 2022, there were two areas of concern in Ukraine - the conflict in the far east of the country (affecting UKDV/Dnipro FIR) and the double claim over ATC and airspace in Crimea (UKFV/URFV/Simferopol FIR).

A civil war has been ongoing since 2014. Some progress made in Oct 2020 with the formation of a new government, but Libya remains an active conflict with armed clashes between various rival militia groups across the country. There is a high risk to civil aircraft. Libyan airspace (HLLL/Tripoli FIR) should be avoided entirely. Total flight ban for US and UK operators, and several other countries have warnings in place.

The primary risk is a misident by Libyan air defense systems, or by militia who have threatened to shoot down aircraft operating in western Libya, including HLLM/Tripoli Mitiga airport. Military activity reported over the high-seas which is either operating as OAT or not in control with ATC. Risk remains high across Libya at all flight levels, and avoidance of all airspace and airports is strongly recommended.

The secondary risk is that reliable ATC services cannot be guaranteed. The past few years have seen regular ATS and radar outages across the HLLL FIR airspace, and severe limitations in VHF capability, with operators having to communicate with Malta ATC for guidance.

Major events:
Jan 2020: Multiple airstrikes targeting HLLM/Mitiga airport. Videos on social media showing planes landing at the airport as shells are falling in the background.
Nov 2019: Militia advancing on the capital, Tripoli, declared a no-fly-zone around the city, threatening to shoot-down civil aircraft attempting to fly to HLLM/Mitiga airport.
Oct 2019: The US issued an emergency order prohibiting US operators from overflying the HLLL/Tripoli FIR except for altitudes at or above FL300 “outside of Libyan territorial airspace” - which is basically the international airspace over the southern Mediterranean Sea that is managed by Libya.
2014: HLLT/Tripoli airport closed after clashes between rival militias destroyed most of the airport's facilities. The airport remains closed to this day; most flights operate out of HLLM/Mitiga airport.

Iraq is an active conflict zone. Local and foreign military continue to fight against an armed insurgency that has existed since 2017. There is a high risk to civil aircraft. Iraqi airspace (ORBB/Baghdad FIR) should be avoided entirely.

The US, Canada, the UK and France have all issued airspace warnings advising against operating in Iraqi airspace at the lower flight levels. The airspace adjoining the Baghdad FIR is also at risk: Iran, Turkey, Syria and Saudi Arabia.
 
The primary risk is intentional targeting by terrorist organisations who possess portable anti-aircraft weaponry. Civil aircraft may also be misidentified by the air defence systems of both local and foreign military who are active in the country. There is a clear risk to civil aircraft operating throughout the FIR at all levels however the eastern airways UL602 (between TAMSI and ALPET), UM860 and UM688 are considered acceptable by France and the UK above FL320.
 
Major events:
Oct 2021: US operators can now overfly the ORBB/Baghdad FIR above FL320. KICZ Notam A0036/20 which banned flights at all levels has been cancelled, and the SFAR now applies.
Jan 2020: US drone strike near ORBI/Baghdad killed a high ranking Iranian general. Considered a serious escalation. Anything that looks like a US asset or ally is now considered a target.
Jan 2020: Ukrainian Airlines 737 misidentified and shot down by Iranian armed forced in Tehran hours after retaliatory missile attacks against US bases in Iraq.
June 2020 onwards: Multiple rocket attacks on ORBI and the US embassy.

US and allied forces have pulled out of Afghanistan, and the Taliban have taken control of the country. Afghanistan’s airspace is now effectively closed to overflights - the OAKX/Kabul FIR is uncontrolled, and overflying traffic should route around the country.

The FAA bans US operators from Afghanistan’s airspace, only permitting overflights on airways P500 and G500 in the far east of the OAKX/Kabul FIR. EASA, along with authorities in several western countries, have issued similar warnings.

The primary risks are direct and indirect fire targeting airports and from surface-to-air fire targeting aircraft operating at low altitudes. Additionally, the conflict has resulted in limited ATC control across the airspace and an extreme threat to aircraft and crew safety and security on the ground.

Major events:
Aug 2021: US and allied military evacuations have finished at OAKB/Kabul airport. It is now under Taliban control. The FAA advises that there are no longer any ATC services available here, along with the entire OAKX/Kabul FIR.
Nov 2020: Major rocket attack in Kabul. Nearly two dozen rockets were fired from vehicles in several neighborhoods around the city causing multiple casualties. The road between OAKB/Kabul Airport and the Intercontinental Hotel was also targeted with an explosive device.

Following the shoot-down of Ukraine Int Airlines flight 752 over Tehran in Jan 2020, several countries issued airspace warnings for Iran, including: the UK, Ukraine, Canada, Germany, and France. The US and Ukraine are the only countries to have issued outright flight bans, but all the others advise against landing or overflying the country at the lower flight levels. The airspace adjoining the Tehran FIR is also at risk: Iraq, Afghanistan and Pakistan.

The primary risk is a misident by Iranian air defense systems. Iran has shown willingness to use long-range, advanced anti-aircraft-capable weapons during heightened tensions and in close proximity to heavily flown international air routes. There is also a potential for Iranian surface-to-surface missile fire from western Iran, targeting terrorist positions in Iraq. The secondary risks come from ballistic missile test launches with no warning by Notam, and GPS jamming (including in overwater airspace over the Persian Gulf and the Gulf of Oman).

Major events:
Jan 2020: Iranian Armed Forces shot-down Ukraine Int Airlines flight 752 over Tehran, having mistaken the aircraft radar return for an inbound missile. Just hours prior to the shoot-down, the US FAA issued “Emergency Order” Notams banning all US operators from overflying the airspace of Iraq and Iran. This was in response to an Iranian missile strike on US military bases in Iraq, which had occurred earlier that night.
June 2019: Iran shot down a US military unmanned aircraft operating in airspace over the Gulf of Oman with a SAM system.
Since 2017: Iran has conducted multiple ballistic missile test launches without issuing any Notams to warn civil operators, the latest taking place in late December 2019.

There has been no major fighting in Ethiopia’s northern Tigray region since late Dec 2021. A ceasefire agreed in March 2022 has mostly been upheld, and Ethiopia’s federal and Tigray regional governments look set for negotiations soon. For the time being though, airspace in the north of the country should still be avoided - several states maintain active airspace warnings for the HAAA/Addis FIR, and Ethiopia still have a Notam in place banning all flights at FL290 and below:



If the conflict resumes, the primary risk to aviation is from misidentification/miscalculation by TPLF or government forces with the use of anti-aircraft weaponry. In other words - civil aircraft being mistaken for something of military interest, or simply caught in the crossfire.


Major Events:

Mar 2022: Militia in Northern Ethiopia have reached a ceasefire agreement with the government. This will hopefully bring an end to the conflict there.

Nov 2021: Six-month nationwide state of emergency declared, following increased fighting between the military and TPLF rebel forces in the north of the country. Several western countries have issued security warnings. The US is now saying “do not travel” to Ethiopia due to armed conflict and civil unrest, and is encouraging those who are in the country to leave. The conflict will likely intensify in the coming weeks - the government has urged people in the capital Addis Ababa to arm themselves, as the northern rebel forces advance to the south.

July 2021: HAAA/Addis FIR published a Notam closing a section of airspace below FL290 over the Tigray region along the Ethiopia/Eritrea border. This follows reports that militia shot down a military transport plane in the region the previous week, near the capital Mekele. Caution if overflying the area, particularly on airways UM656/UT124 between the HSSS/Khartoum and HAAA/Addis FIRs which have previously been closed due to the conflict.

Nov 2020: Major escalation of the conflict in the Tigray region, along the Ethiopia/Eritrea border. Some airways were closed by the Ethiopian and Sudanese CAAs. Other airways that were still open were very close to the conflict zone. These are frequently used by international operators on the Europe-East Africa route. In particular: UN321, UG300 and UL432. Multiple airports were targeted by rockets. Missiles were fired across the border into Eritrea, targeting HHAS/Asmara. Within Ethiopia, HABD/Bahir Dar and HAGN/Gondar were also targeted.

Sep 2018: Risk due to hidden ATC strike. Ethiopian ATC controllers went on strike, and the ECAA and Ethiopian Airlines recruited both retired and foreign controllers to pick up the slack. Ethiopia denied several times that there was in fact a strike happening at all. The strike ended September 7th. Many were not qualified to operate in Ethiopian airspace, due to inexperience.

Improving airspace risk picture in Saudi Arabia, where there have been no reported drone strikes from Yemen since a ceasefire was agreed in April - which has now been extended to Aug 2. All groups have agreed to halt the conflict inside and outside Yemeni borders.

If the conflict resumes, Houthi drone and missile attacks on targets in Saudi Arabia pose a potential threat to ops at Saudi airports, and for overflights of the OEJD/Jeddah FIR. The most significant risk is in the south of the country along the border with Yemen, but OERK/Riyadh and OEJN/Jeddah airports have also been targeted in the past.

The are several long-standing airspace warnings in place: Canada, France and Germany warn of a risk to landing anywhere in the country, but particularly along the border with Yemen in the southwest part of the OEJD/Jeddah FIR. There is definitely a risk to operations in Saudi airspace, even outside the ESCAT area.

The primary risk is from Houthi drone and missile attacks on airports across the country, but particularly in the south.
 
Major events:
June 2022: All parties in the Yemeni conflict have agreed to extend a ceasefire to August 2. No reported drone strikes in Saudi Arabia since the ceasefire began on April 2.
2020-2022: Frequent Houthi drone and rocket attacks targeting OEAH/Abha and OEGN/Jizan airports along the Yemeni-Saudi Border.
Sep 2020: Multiple Saudi airstrikes on rebels in Sanaa, several near the airport.
Oct 2020: Riyadh briefly on high alert for Houthi cruise missile and drone attack.

There is an ongoing active conflict in Ukraine between Russian and Ukrainian forces. Ukraine closed its entire airspace to all civil traffic on Feb 24. Russia and Belarus have closed large sections of their own airspace near to their FIR boundaries with Ukraine. Moldova initially closed all their airspace too, but have now opened a section on their western border with the LRBB/Bucharesti FIR for flights to LUKK/Chisinau airport.

The primary risk is an unintended targeting of civil aircraft by military near the Moldova-Ukraine border, including misidentification (as with MAS17, UIA752), or confusion.

Read: OPSGROUP article: Ukraine and Russia Update March 2022

The situation on the ground is highly unstable and there is an inherent risk to civilians and aircraft. The central government has little control of the major cities and ports, with ongoing attacks from extremist militants targeting civilians who continue to show an intent to target aviation interests.

The primary risk is to overflying aircraft at the lower flight levels, which may be targeted by anti-aircraft-capable weapons. The US prohibits flights across Somalia’s airspace below FL260. Several other countries have issued airspace warnings advising against operating below FL260 (Note UR401 SIHIL-AXINA is excluded from this by one authority).

The secondary risk over the past few years has been the lack of ATC service for overflights of the HCSM/Mogadishu FIR - it has been Class G uncontrolled airspace. However, from 11 May 2022 there’s a new trial implementing Class A airspace here above FL245 each day from 0300-1800z. More info here.

Major events:
2020-ongoing: Multiple instances of Al-Shabaab attacks on HCMM/Mogadishu and nearby targets, including a UN compound.
May 2020: An Embraer EMB-120 was shot down while on approach to Bardale airstrip, killing all six people on board - an accidental shoot-down by Ethiopian forces stationed in the region to combat Al-Shabaab.

Read: OPSGROUP article: Al-Shabab: A Threat Beyond Somalia, Jul 2021

There remains a threat from terrorism in Egypt, particularly in the Sinai Peninsular. Only the UK and Germany still have active airspace warnings here - both countries essentially advise against overflights below FL260 in the northern part of the Sinai region. The US had a similar warning in place until it was rescinded in March 2022.



Major events:
July 2019: British Airways suspends Cairo operations for one week due to security concerns.
Feb 2017: An SA-7 anti-aircraft missile tube was found less than a mile from HECA/Cairo airport.
Oct 2015: A Russian A321 was brought down over the Sinai peninsula by a bomb loaded at HESH/Sharm El Sheikh. The group claimed the IED was placed aboard the aircraft prior to departing HESH, raising concerns of potential insider threats at the airport.

Ukraine closed its entire airspace to all civil traffic on Feb 24, 2022, due to a military invasion by Russia. There is an ongoing active conflict in Ukraine between Russian and Ukrainian forces. Russia, Belarus and Moldova have closed large sections of their own airspace near to their FIR boundaries with Ukraine.

The US and Canada have since banned their operators from the section of airspace in Russia along its FIR boundaries with Ukraine, and several other countries have issued airspace warnings for this area (we have not listed them all here due to sheer volume).

The primary risk is an unintended targeting of civil aircraft by military near the Russia-Ukraine border, including misidentification (as with MAS17, UIA752), or confusion.

There is an ongoing active conflict in Ukraine between Russian and Ukrainian forces. Ukraine closed its entire airspace to all civil traffic on Feb 24. Russia and Belarus have closed large sections of their own airspace near to their FIR boundaries with Ukraine.

The US has issued an outright ban barring its operators from the entire airspace of Belarus, and several other countries have issued warnings for the section of airspace in Belarus along its FIR boundary with Ukraine. Several other countries have also issued warnings for this airspace - we have not listed them all here due to sheer volume.

The primary risk is an unintended targeting of civil aircraft by military near the Belarus-Ukraine border, including misidentification (as with MAS17, UIA752), or confusion.

Read: OPSGROUP article: Ukraine and Russia Update March 2022

Prior to Feb 2022, several countries and aviation organisations had urged airlines and operators to avoid the airspace of Belarus, following the country’s interception of an international flight bound for Lithuania and forced to land in Minsk on May 23, 2021. The forced landing of this flight was politically motivated, and the crew were misled into believing that there was a credible security threat against the aircraft.

Following talks with the US in early 2018, North Korea agreed with ICAO that it would provide adequate warning of all “activity hazardous to aviation" within its airspace. However, in May 2019 North Korea resumed launching missiles into the Sea of Japan, without providing any warning by Notam.

The US prohibits flights across all North Korean airspace, including the oceanic part of the ZKKP/Pyongyang FIR over the Sea of Japan. Several other countries have airspace warnings in place which advise caution due to the risk posed by unannounced rocket launches.

The primary risk is from debris from missile re-entries striking aircraft overflying the oceanic part of the ZKKP/Pyongyang FIR over the Sea of Japan. Consider rerouting to remain over the Japanese landmass or east of it.

Major events:
2021: North Korea tested some short-range ballistic missiles, and a new long-range cruise missile with a range capable of hitting Japan.
2017: North Korea launched two intercontinental ballistic missiles. Both of these landed in the Sea of Japan, well inside the Fukuoka Flight Information Region (Japanese airspace), and significantly, at least one did not re-enter the atmosphere intact – meaning that a debris field of missile fragments passed through the airspace, not just one complete missile.
2015: North Korea gradually stopped notifying ICAO of missile launches, so that aircraft could avoid the launch and splashdown areas.

Kenya is affected by the ongoing Somali Civil War - the main threat comes from militants in response to Kenya’s military intervention in Somalia. The US has a warning in place to exercise caution below FL260 in Kenya’s airspace east of 40 degrees East longitude (the border region with Somalia).

The primary risk is from indirect mortar and rocket fire, including MANPADS, which could target aircraft at low altitudes and at airports.

Major events:
Jan 2020: Two US military/govt aircraft (C-146A, DHC-8), and two helicopters, were destroyed in a militant attack on HKLU/Manda Airport, a US/Kenya joint military base in Lamu county, east coast. Security concerns in this part of Kenya have been ongoing for several years.

Jan 2019: Al-Shabaab militants launched an attack on a hotel complex in central Nairobi on 15 Jan 2019, killing at least 14 people. There were a number of attacks by Al-Shabab in Kenya in preceding years, but none in Nairobi since the attack on the Westgate shopping mall in 2013.

The northern Mali War has been ongoing since 2012, and there have been no improvements in stability. The US, Germany, France and the UK all have warnings in place, advising to operate FL250/260 or higher, and avoiding GATB, GAGO, and GAKL airports, due to ongoing fighting and militant activity. We would suggest, as usual, that a higher level closer to FL300 is more sensible.

The primary risk is from indirect mortar and rocket fire, including MANPADS, which could target aircraft at low altitudes and at airports. The FAA say that militants in Mali primarily target UN and Malian forces which are often based near to Malian airports, and these attacks present an indirect threat to civil aviation.

Major events:
Aug 2020 All airports across the country were closed from Aug 19-20 following a military coup which overthrew the government. Bamako ACC remained operational throughout, with overflights unaffected.
April 2018: Militants attacked UN peacekeepers at two bases near GATB/Timbuktu Airport using both indirect fire weapons and vehicle-borne improvised explosive devices.
Jan 2017 and Nov 2016: Militants conducted vehicle-borne improvised explosive attacks against GAGO/Gao Airport, and rocket attacks against GATB/Timbuktu Airport.

Senegal and Niger control the airspace over Mali, and they have long-standing Notams (published under the GOOO/Dakar and DRRR/Niamey FIRs) warning that you can only fly between FL320-400 through the entire airspace in Mali north of the GABS/Bamako TMA due to military ops across the region.

Following five years of civil war, a ceasefire has largely held since Sept 2018. Significant reduction in violence, but the political and security situation remains volatile. In the event of a serious deterioration, similar to those of July 2016 and Dec 2013, HSSJ/Juba airport may be closed at short notice. The UK, France and Germany still advise against overflying South Sudan below FL250/260 due to the risk posed by anti-aircraft weaponry. The US published a similar warning but rescinded it in Aug 2019.

The primary risk now comes from poor levels of ATC provision for overflights below FL245 or for aircraft operating to HSSJ/Juba airport. In Jan 2021, ICAO published a letter warning of service disruptions and lack of qualified ATC personnel, the lack of contingencies in place, communication issues, the number of withdrawn navigation aids and above all, the lack of information being supplied to operators regarding these issues.

Major events:
April 2019: Military coup in Sudan led to the temporary closure of South Sudan’s airspace.
June 2016: The South Sudanese army declared intention to shoot down aircraft without permits and/or not following proper procedures.

HHAS/Asmara airport was targeted on 14 Nov 2020 by missiles from the Tigray TPLF, bringing Eritrea into the conflict and meaning that operations here should be avoided. See Ethiopia summary for more detail.

Couple of issues: Conflict with India in the Kashmir region in the northeastern corner of Pakistan, and concentration of terrorist group representation in the country. Military activity by Pakistan and India in the disputed Kashmir region poses a potential inadvertent risk to aviation at all altitudes, particularly in the OPLR/Lahore FIR. The consensus among foreign authorities is to cross the OPLR/Lahore and OPKR/Karachi FIRs at higher flight levels. Diversion/Landing in Pakistan is recommended against. Avoid operating to OPPS/Peshawar and OPQT/Quetta airports - both are near the border with Afghanistan. OPKC/Karachi Airport was attacked in 2014.

Increasing reports of drone and missile attacks on the UAE by Houthi militants in Yemen. OMAA/Abu Dhabi Airport has been targeted on several occasions. The Houthi have suggested they will continue to target sites in the UAE. There are not currently any official airspace warnings for the OMAE/Emirates FIR by any countries, but we are listing this info here for reference.

The primary risk is from incidental damage from Houthi drone and missile attacks on airports. Also note that short notice airspace disruptions are likely, along with air defence activity near major cities.

Major events:
Feb 2022: At least three drones were shot down by surface-to-air missiles in UAE airspace on Feb 2. This time militants in Iraq have claimed responsibility for the attack.
Jan 2022: Houthi ballistic missile targeting Abu Dhabi was destroyed on Jan 30 - the third attack in two weeks. Flights at OMAA/Abu Dhabi were briefly affected.

Ops resumed at HSSK/Khartoum Airport on Oct 27 following a military coup in Sudan on Oct 25. The main risk to aviation is the security situation on the ground. Civil unrest is widespread and there have been fatal clashes with police. There's no increased risk for overflights in the HSSS/Khartoum FIR, but keep in mind the lack of security if you need to divert - things are volatile.

Only one international airspace warning exists, that of France, recommending overflight above FL260 in the far southern and western edges of the country (west of the 27°E and south of 13°N) near to the borders with South Sudan, Central African Republic, and Chad.

The primary risk here now relates to its proximity to South Sudan - which has poor levels of ATC provision for overflights below FL245.

Major events:
Oct 2021: Military coup on Oct 25. HSSK/Khartoum closed for two days, with all flights suspended.
Jan 2020: HSSK/Khartoum airport was closed for five hours late on 14 Jan following gunfire on the streets of the capital, including in areas close to the airport. The clashes were between the army and former security agents who revolted over severance pay. The airport reopened the next day, with the government saying the violence was over and the situation was under control.
Apr 2019: Sudan temporarily closed its airspace all day on 11 April following a military coup which ousted the country’s longtime President Omar al-Bashir from power. This came after months of on-and-off protests against his rule.

Rocket attacks on Israel and Israeli air strikes on targets in Gaza and Syria could present a risk to civil aircraft operating in the region.

The primary risks are: misidentification or miscalculation by air defence systems, falling debris from air defence activities, ballistic impact while on the ground, and short notice airspace closures.

Major Events:
Aug 2021: Following an Israeli airstrike on Syria, Syria sent a surface to air missile towards Tel Aviv. The missile detonated off the coast of Israel and there was no damage.
May 2021: Rocket attacks on Israel and Israeli air strikes on Gaza. LLBG/Tel Aviv Airport was forced to close on several occasions, as air defence systems were activated around the country to repel incoming rocket attacks. Ceasefire agreed on May 21.
July 2014: Major rocket fire from Gaza against Tel Aviv during the Gaza War. The US FAA responded by imposing restrictions at LLBG/Tel Aviv airport for a two day period, and EASA advised that operators suspend flights, which ultimately resulted in 30 airlines cancelling flights.

Read: Opsgroup article - Israel: Assessing the Airspace Risk, May 2021

The primary risk is misidentification by local militia who infrequently target Turkish military aircraft with MANPADS and weaponsied drones. Operations to LTAJ/Gaziantep should be carefully reviewed given its proximity to the Syrian border.

The secondary risk is from GPS jamming. There are frequent reports from crews of GPS signal interference in Turkish airspace - with some as far away as abeam Baghdad. GPS jamming is common through the LTAA/Ankara FIR, and especially on the border between the ORBB/Baghdad and OIIX/Tehran FIRs.

Major events:
May 2021: Attempted drone attack by local militia on LTCC/Diyabakir airport in South Eastern Turkey.
Jan 2019: Turkish security forces intercepted three weaponised drones during attempted attacks against sites in southern Turkey.

A new conflict zone is emerging in Western Sahara. The country is split down the middle - Morocco controls the west, and the region’s independence movement, the Polisario, controls the east. The Polisario have declared war on Morocco.

The primary risk is from anti-aircraft fire from the conflict. The FAA has published a note warning that the Polisario likely have access to anti-aircraft weaponry which may pose an inadvertent risk to civil aircraft up to FL120. The GCCC/Canarias FIR has issued a Notam warning operators to avoid using the airways over Western Sahara below FL200.

The secondary risk is from lack of continuous ATC coverage. Western Sahara does not control its own airspace - it falls within both the GCCC/Canarias and the GOOO/Dakar FIRs, which may complicate airspace management should the conflict escalate. The FAA advise aircraft operating in the region to stay in touch with ATC and be prepared for possible airspace restrictions and reroutes.

Pilots should exercise extreme caution while operating in Albanian airspace (the LAAA/Tirana FIR) due to a heightened risk of degraded ATC services.

On April 8, Albanian airspace (the LAAA/Tirana FIR) along with LATI/Tirana Airport was forced to close, after a number of local air traffic controllers declared themselves temporarily unfit to work.

Local air traffic controllers are working under significant duress and high stress, having been threatened with dismissal (or worse - being arrested and jailed) if they do not declare themselves fit for duty. A number of foreign controllers were temporarily brought in despite not being trained or rated on any of the local positions.

Several international associations have published warnings, including IFALPA and IFATCA.

The primary risk is from debris from missile re-entries striking aircraft overflying the oceanic part of the ZKKP/Pyongyang FIR over the Sea of Japan. North Korea regularly conducts unannounced missile tests in this area. Consider rerouting to remain over the Japanese landmass or east of it.

The US prohibits flights across all North Korean airspace, including the oceanic part of the ZKKP/Pyongyang FIR over the Sea of Japan. Several other countries have airspace warnings in place which advise caution due to the risk posed by unannounced rocket launches.

Major events:
2021: North Korea tested some short-range ballistic missiles, and a new long-range cruise missile with a range capable of hitting Japan.
2017: North Korea launched two intercontinental ballistic missiles. Both of these landed in the Sea of Japan, well inside the Fukuoka Flight Information Region (Japanese airspace), and significantly, at least one did not re-enter the atmosphere intact – meaning that a debris field of missile fragments passed through the airspace, not just one complete missile.
2015: North Korea gradually stopped notifying ICAO of missile launches, so that aircraft could avoid the launch and splashdown areas.

Ongoing political and social crisis in Venezuela. On 1 May 2019, the US FAA issued a new Do Not Fly instruction to US operators, barring all operations into or over Venezuela, unless operating at or above FL260, and giving a window of 48 hours to leave the country.

The primary risk in Lebanon’s airspace (the OLBB/Beirut FIR) relates to its proximity to Syria: civil aircraft may be targeted in error, or caught in crossfire during ongoing air attacks involving Israel, Russia, Iran. Missiles may erroneously lock on to civil aircraft. There is a risk to civil aircraft operating on airways UL620, UW74, UR18, and UP62. In simple terms, if you find yourself planned overwater east of Cyprus, reconsider your route.

Several countries have issued airspace warnings for Syria, banning operators from entering the OSTT/Damascus FIR. Many of these warnings include include the note that there is a potential risk to aircraft within 200nm of the Damascus FIR (i.e. the LLLL/Tel Aviv, OJAC/Amman, OLBB/Beirut and LCCC/Nicosia FIRs) due to military activity - possibility of GPS interference, communication jamming, and long-range surface to air missiles in the area.

Major events:
Feb 2020: An A320 enroute OSDI/Damascus caught in crossfire during attack by 4 Israeli F-16’s, forced to divert to Russian controlled air base.
Sep 2018: Russian IL-20 shot down in error on FIR boundary with Cyprus (Nicosia FIR) - airline flights on UL620 within 50nm of this position.

N'Djamena in the past was a popular fuel stop in central Africa, but multiple travel warnings now advise against travel here. No official state Notams have been issued, but danger remains high.  A state of emergency remains in place for the Lake Chad region. High threat for terrorism. Avoid landings.

Two issues the LCCC/Nicosia FIR over Cyprus: proximity to active conflict zone in Syria, and GPS Interference.

The primary risk is from the proximity to Syria: civil aircraft may be targeted in error, or caught in crossfire during ongoing air attacks involving Israel, Russia, Iran. Missiles may erroneously lock on to civil aircraft. There is a risk to civil aircraft operating on airways UL620, UW74, UR18, and UP62. In simple terms, if you find yourself planned overwater east of Cyprus, reconsider your route.

The secondary risk is from GPS Interference. This has been ongoing since 2018. In April 2018, the Nicosia FIR began being used as a military staging for possible strikes in Syria, prompting EASA to issue a warning, and lead to avoidance of the FIR by many airlines.

Major events:
Sep 2018: Russian IL-20 shot down in error on FIR boundary with Cyprus (Nicosia FIR) - airline flights on UL620 within 50nm of this position.

There has been a high volume of crew reports of GPS Interference in the Philippines, leading to GPS/ADS-B dropouts, especially in the vicinity of RPLL/Manila.

The situation on the ground in the Central African Republic is volatile and as of June 2017 has been deteriorating rapidly. There have been numerous attacks on Civilians and peacekeeping troops. Bangui FEFF is operating under UN control, it is subject to regular power outages and is also acting as a refugee camp. Avoid landings.
