A U.S. drone strike killed an Islamic State group leader in Syria hours after the same MQ-9 Reaper drones were harassed by Russian military jets over the western part of the country, according to the Defense Department.
Three Reapers had been flying overhead searching for the militant on Friday, a U.S. defense official said, when they were harassed for about two hours by Russian aircraft. Shortly after that, the drones struck and killed Usamah al-Muhajir, who was riding a motorcycle in the Aleppo region, said the official, who was not authorized to publicly discuss the matter and spoke on condition of anonymity to describe details of the military operation.
