A U.S. service member was killed by an improvised explosive device in northern Syria on Thursday, the Pentagon announced in a statement. The service member was killed near Ayn Issa, a town roughly 35 miles northwest of the Islamic State’s self-proclaimed capital of Raqqa. The death marks the first time a U.S. service member has been killed in the country since a contingent of Special Operations forces were deployed there in October 2015 to go after the extremist group.
