A Syrian warplane has crashed near the capital, but it's unclear if it was shot down or came down because of a technical fault.
The British-based Syrian Observatory for Human Rights monitoring group said on September 21 that the aircraft crashed north of Damascus.
Syrian state media reported that the warplane crashed after carrying out a combat mission against the Islamic State (IS) group, and that the pilot was rescued.
The cause of the crash was not given.
The IS-affiliated Amaq news agency said the militants downed the plane after the aircraft carried out four raids against it.
The group claimed on September 18 to have shot down another Syrian warplane that crashed in eastern Syria.
