Reuters reports an American man has been charged with trying to provide support for the Islamic State militant group, the U.S Justice Department said on Thursday. Joshua Ray Van Haften, 34, of Madison, Wisconsin, intended to travel to Iraq or Syria to join the militant group, also known by the acronyms ISIL or ISIS, prosecutors said in a statement. Van Haften was due to make an initial appearance in federal court in Madison on Thursday. He was arrested at Chicago's O'Hare International Airport on Wednesday night after arriving on a flight back from Turkey. If convicted, he faces up to 15 years in prison. Prosecutors allege that Van Haften left the United States on August 26, 2014, bound for Turkey, an intermediary stop for many would-be fighters due to the border it shares with Syria.
