Gruesome post-beheading pic here.

Via HuffPo:

Supporters of the Islamic State group circulated an image on social media on Wednesday appearing to show the beheaded body of a Croatian hostage who was kidnapped in Egypt last month.

Tomislav Salopek, a 30-year-old petroleum engineer, was captured in the Egyptian capital of Cairo last July, Egypt’s foreign ministry said. On August 5, a video circulating online appeared to show Islamic State loyalists in Sinai threatening to kill Salopek within 48 hours unless Egyptian authorities released Muslim women in their custody. Friday’s deadline passed without word of Salopek’s fate.

A caption on the still image purporting to show Salopek’s body states in Arabic he was killed “for his country’s participation in the war against the Islamic State,” the Associated Press reports.

The Huffington Post could not independently verify the image.

Croatia’s foreign ministry could not confirm Salopek’s death, the Associated Press reports. However, Croatia’s prime minister will be addressing the nation in a couple of hours.
