I read the OP. Didn't you?
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.
