Israel says it has shot down a Syrian fighter jet over its airspace.
The aircraft was intercepted in mid-flight over the Quneitra area of the Golan Heights, the Israeli Defence Forces (IDF) said.
A Patriot missile was fired at the jet, identified in Israeli media reports as a MiG-21.
The Golan area, which was captured by Israel in the 1967 Middle East war, has seen clashes between the al Qaeda-linked Nusra Front and Syrian President Bashar al Assad’s forces in recent weeks.
Syrian state TV confirmed Israel had shot down the plane, and described it as an act of aggression.
It quoted a military source saying the attack came “in the framework of (Israel’s) support for the terrorist (Islamic State) and the Nusra Front”.
It came hours after the US and five Arab countries began airstrikes against Islamic State targets in Syria for the first time.
The aerial raids were carried out using fighter jets, bombers, drones, and Tomahawk cruise missiles launched from US ships in the northern Persian Gulf and the Red Sea.
Saudi Arabia, the United Arab Emirates, Jordan, Bahrain and Qatar were involved in the raids, a US official said, although their exact roles were unclear.
