A U.S. strike aircraft shot down a Syrian government fighter jet shortly after it bombed U.S.-backed Syrian fighters in North Syria, the Pentagon said in a statement Sunday.

The Pentagon said the shoot-down came hours after Syrian government-backed forces attacked U.S.-backed fighters, known as the Syrian Democratic Forces, in the village of Ja'Din. As the attack unfolded, the U.S. military used a deconfliction channel to communicate with the Syrian government to stop the skirmish, according to the Pentagon statement.

Roughly two hours later, despite the called-for stand down, a Syrian Su-22 jet dropped an unknown number of munitions on the Syrian Democratic Forces. A U.S. F/A-18 promptly shot the Syrian aircraft down "in accordance with rules of engagement and in collective self-defense of coalition partnered forces," the Pentagon statement said.

The incident comes almost two weeks after a U.S. jet downed a pro-Syrian government drone that threatened U.S.-led coalition forces in southern Syria.
