Iraqi forces on Friday captured the border town of Rawa, the last remaining town under Islamic State control, signaling the collapse of the group’s self-proclaimed caliphate. Rawa’s capture marks the end of Islamic State’s era of territorial rule over a so-called caliphate that it proclaimed in 2014 across vast swathes of Iraq and Syria. Iraqi forces “liberated Rawa entirely, and raised the Iraqi flag over its buildings,” Lieutenant General Abdul Ameer Rasheed Yarallah said in a statement from the Joint Operations Command.
