A U.S. warplane shot down a Syrian army jet on Sunday in the southern Raqqa countryside with Washington saying the jet had dropped bombs near U.S. backed forces and Damascus saying the plane was downed while flying a mission against Islamic State militants.
A Syrian army statement released on Syrian state television said the plane crashed and the pilot was missing. It said the incident took place on Sunday afternoon near a village called Rasafah.
The "flagrant attack was an attempt to undermine the efforts of the army as the only effective force capable with its allies ... in fighting terrorism across its territory," the Syrian army said.
"This comes at a time when the Syrian army and its allies were making clear advances in fighting the Daesh (Islamic State) terrorist group."
