“On Sunday evening, a U.S. warplane shot down a Syrian jet after it bombed American-backed rebels in northern Syria. This marked the first time the United States has downed a Syrian warplane since the start of the country’s civil war in 2011. On Tuesday, the Pentagon announced that the United States had shot down an Iranian-made drone in the country’s southeast, where American personnel have been training anti-Islamic State fighters.”
