Syria
Risk Level: Two - Danger exists
[ about risk levels ]
Oct 2026: The OSTT/Damascus FIR remains high risk, although some regional operators have resumed overflights as an alternative to Iran and Iraq routings. EASA now permits flights at FL260 and above in most of the FIR, but prohibits operations at all levels in the western part. Several countries continue to advise against or prohibit operations in Syrian airspace.
See OPSGROUP Briefing: Middle East airspace situation - 2026
The primary risk is ongoing military activity, including Israeli airstrikes and missiles and drones being intercepted over Syria. Drones, rockets and MANPADS are an additional threat at lower levels. The risk is highest in south-western Syria and at lower levels, but can increase across the FIR if the wider regional conflict escalates.

Major events:
Oct 2026: EASA revised its guidance, prohibiting flights in western Syria at all levels and below FL260 elsewhere in the FIR.
Mar 2026: OSTT/Damascus FIR closed following US and Israeli strikes on Iran.
Dec 2024: Syrian airspace closed following the fall of the Assad regime.
Oct 2023: Airstrikes damaged runways at OSDI/Damascus and OSAP/Aleppo.
Feb 2020: An A320 diverted after being caught in crossfire near Damascus.
Sep 2018: A Russian Il-20 was shot down in error near the Syria-Cyprus FIR boundary.

Plain English: US operators are prohibited from entering the OSTT/Damascus FIR.
This action extends the prohibition against certain flight operations in the Damascus Flight Information Region (FIR) (OSTT) by all: U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when the operator of such aircraft is a foreign air carrier, for an additional five years, from December 30, 2023, until December 30, 2028. The FAA finds this action necessary to address significant safety-of-flight risks to U.S. civil aviation associated with the enduring complex conflict in Syria. The FAA also republishes the approval process and exemption information for this Special Federal Aviation Regulation (SFAR), consistent with other recently published flight prohibition SFARs.

Plain English: An errant surface-to-air missile fired by Syrian air defences missed its target and landed in Israel on 22 Apr 2021. Syria is actively using long range anti-aircraft weaponry which poses a risk to civil aircraft in the region. While US operators are banned from the OSTT/Damascus FIR, the FAA warns the threat is extended to adjacent FIRs in the Eastern Mediterranean region including the LLLL/Tel Aviv, OJAC/Amman, OLBB/Beirut and LCCC/Nicosia FIRs. Use caution if operating in the area.

Plain English: Operators should not enter the airspace of Syria.
This CZIB is issued based on information currently available to EASA, the European Commission and Member States in order to share information which is considered necessary to ensure the safety of flights over zones of interest and indicate areas of high risk.
The airspace over Syria continues to be affected by the presence of multiple military forces, including State and non-state actors, as well as recurrent foreign military operations.
The risk of Israeli strikes and other military activities contribute to an overall volatile situation with the potential for rapid and unpredictable escalation.
In terms of airspace management, fragmented control of the airspace and limited coordination mechanisms reduce the effectiveness of deconfliction and the timely dissemination of relevant information.
The presence and potential activation of air defence systems, combined with ongoing military activity and a high level of alert among military forces, increase the likelihood of misidentification of civil aircraft. In addition, the presence of violent non-state actors with the capability to use unmanned aerial systems, rockets and MANPADS creates additional risks in the airspace.
The combination of active military operations, air defence capabilities and limited mitigating factors results in a high risk to civil aviation at all altitudes and flight levels.
Air operators should:
1. Not operate in the airspace of Syria at all altitudes and flight levels.
2. Closely monitor airspace developments in the region and follow all available aeronautical publications issued by Syria, or on their behalf by the Aviation Authorities of the neighbouring States, including information shared through the European Information Sharing and Cooperation Platform on Conflict Zones, alongside available guidance or direction from their national authorities.

Plain English: Operators should not fly in the western part of the OSTT/Damascus FIR (west of the ZELAF–BASEM–LOTAX–LATEB line). Elsewhere in the FIR, flights below FL260 are also prohibited.
This CZIB is issued based on information currently available to EASA, the European Commission and Member States in order to share information which is considered necessary to ensure the safety of flights over zones of interest and indicate areas of high risk.
The airspace over Syria continues to be affected by the wider regional security dynamic, the presence of multiple State and non-State actors, as well as recurrent foreign military operations.
Iranian missile and UAS transits towards Israel and US/Jordanian targets remain recurrent, but largely escalation driven. Their direct impact on civil overflights of Syria is generally assessed as limited due to the trajectories involved. However, interception activity against Iranian ballistic missiles targeting Israel or Jordan may create high risks to civil aviation in particular in south-western Syrian airspace. In addition, interceptions of ballistic missiles targeting Israel may take place at considerable distances from Israeli airspace and may result in falling debris affecting other parts of Syrian airspace.
Israeli military strikes against targets in Syria remain recurrent, although they are generally limited in duration and concentrated in the south-west of the country. At the same time, the overall degradation of Syria’s long-range air-defence network has reduced the risk of misidentification and unintended engagement of civil aircraft. Air-defence systems associated with other State actors are assessed as primarily providing localised protection of specific areas and are not currently considered to have a significant direct impact on civil overflight operations.
At lower altitudes, violent non-State actors retain capabilities, including UAS, rockets and MANPADS, creating additional risks primarily below FL260.
Available data also indicate that kinetic and associated air-defence activity is concentrated predominantly during the hours of darkness.
While improvements have been observed in the dissemination of aeronautical information and the management of conflict-related risks, fragmented control of the airspace and limited coordination mechanisms continue to constrain effective deconfliction and the timely dissemination of relevant information.
Overall, the main risks to civil aviation remain concentrated in the south-western parts of Syria and at lower altitudes across the country. At higher altitudes, the risk to overflights is reduced. Nevertheless, regional escalation in the Middle East may result in missile and UAS activity, associated interceptions and falling debris, temporarily increasing risk exposure, including at higher flight levels.
EASA, together with the Commission and Member States, will continue to closely monitor the situation, with a view to assess whether there is an increase or decrease of the risk for EU aircraft operators due to the evolution of the threat and risk situation.
Air operators should:
1. Not operate at all flight levels and altitudes, west of the line connecting navigation points ZELAF – BASEM – LOTAX - LATEB, including airways segments forming this boundary.
2. Not operate below FL 260 in the remainder of the FIR Damascus (OSTT).
3. Exercise caution and take potential risks into account when operating at and above FL260 in the portion of the Damascus FIR (OSTT) not covered by point 1 above.
4. Consider scheduling operations during daylight hours as an additional risk-mitigation measure.
5. Ensure that an up-to-date risk assessment and a high level of contingency planning are in place for operations within the affected airspace, and be prepared for short notice instructions from the State authorities.
6. Closely monitor airspace developments in the region and follow all available aeronautical publications concerning the region, including information shared through the European Information Sharing and Cooperation Platform on Conflict Zones, alongside available guidance or direction from their national authorities.
