Qaraqosh, a largely Assyrian City just 32km southeast of Mosul was taken by ISIS in August of 2014 forcing all residents to flee, the town was largely destroyed with all of the churches burned or heavily damaged. The town stayed under ISIS control until the previous week when it was liberated during the Mosul Offensive. #
