The Israeli military is claiming to have shot down the plane. The condition of the pilot is unclear.
Earlier the Israeli military said in a statement it had “intercepted” a Syrian warplane that penetrated Israeli-controlled airspace.
The statement said two Patriot interceptor missiles were launched at the Sukhoi jet after it crossed 2km “into Israeli territory” - a possible reference to the occupied Golan Heights on the Syrian front.
According to Syria's Sana news agency, Israeli fighter jets have recently bombarded a scientific research centre in the Syrian city of Masyaf, located in Hama province.
According to some reports, Israeli fighter jets entered Syrian airspace from Al-Boqa district which is in Lebanese territory , close to Syria's border with Lebanon.
