Recent Turkish air strikes in northern Syria threatened the safety of U.S. military personnel and the escalating situation jeopardized years of progress against Islamic State militants, the Pentagon said on Wednesday.
"Recent air strikes in Syria directly threatened the safety of U.S. personnel who are working in Syria with local partners to defeat ISIS and maintain custody of more than ten thousand ISIS detainees," the Pentagon's spokesman, Air Force Brigadier General Pat Ryder, said in a statement.
