An Egyptian militant group linked to ISIL has released a video threatening to kill a Croatian hostage within 48 hours unless Egypt releases female Muslim prisoners. The video shows a man kneeling in a jumpsuit in front of a masked man with a knife. He identifies himself as Tomislav Salopek, an employee of a French geoscience company that provides seismic data for the oil and gas industry. The militant group behind the video and the kidnapping is reported to be the Sinai Province, which pledged allegiance to ISIL in 2014. The video’s release comes as Egypt prepares to host hundreds of foreign officials at today’s inauguration of the $8.5 billion expansion of the Suez Canal.
