Online image purports to show Croat killed by Islamic State

1CAIRO (AP) " An online image circulated Wednesday purported to show a Croatian hostage held by the Islamic State group's Egyptian affiliate beheaded.
2The still image, shared by Islamic State sympathizers on social media, showed the apparent body of Tomislav Salopek, a married, 30-year-old father of two, wearing a beige jumpsuit looking like the one he had worn in a previous video.
3A black flag used by the Islamic State group and a knife were planted in the sand next to him.
4The photo carried a caption in Arabic that said Salopek was killed "for his country's participation in the war against the Islamic State," and after a deadline had passed for the Egyptian government to meet their demands.
5This comes after the Islamic State affiliate set a Friday deadline for Egyptian authorities to free "Muslim women," a term referring to female Islamist prisoners detained in a sweeping government crackdown following the 2013 military ouster of an Islamist president.
