A Syrian monitoring group says a warplane has crashed northwest of the capital, Damascus, as Islamic State group militants claim they downed it.
The Britain-based Syrian Observatory for Human Rights says the fate of the pilot remains unclear. It says it was unclear if the warplane was downed Wednesday or had technical problems.
The Observatory says the plane crashed in the eastern Qalamoun mountains, northwest of Damascus.
The ISIS-affiliated news agency Aamaq says the group's militants downed the plane in eastern Qalamoun, after the aircraft carried out four raids against it. The agency says the plane crashed in an area controlled by either the government or rebel factions, indicating it would not have pictures of the aircraft.
