Online image purports to show Croat killed by ISIS

An online image circulated Wednesday purported to show a Croatian hostage held by the ISIS group's Egyptian affiliate beheaded. The still image, shared by ISIS sympathizers on social media, showed the apparent body of Tomislav Salopek. A black flag used by ISIS and a knife were planted in the sand next to him. The photo carried a caption in Arabic that said Salopek was killed "for his country's participation in the war against ISIS," and after a deadline had passed for the Egyptian government to meet their demands.
