There are many headlines expressing concern about young British people leaving this country to join the so-called Islamic State. But now Islamic State (IS) militants are targeting a new group of potential recruits in the west – deaf people. In a video, which is reported to have been released last Sunday, two deaf IS fighters who communicate in sign language were shown appealing for other deaf people to join them. The video features what may be an Arabic form of sign language – it is not British or American Sign Language but may be a form of International Sign. It includes subtitles in both English and Arabic. It looks professionally made, and shows the two men directing traffic while heavily armed with guns. It is from the Nineveh Province, which is under IS control. It also includes footage from the city of Mosul.
