(BARTELLA, Iraq) — Iraqi forces shelled Islamic State (ISIS) positions outside Mosul on Monday as fighting to retake the extremist-held city entered its second week. A rights group, meanwhile, urged a probe into a suspected airstrike last week that mistakenly hit a mosque, killing over a dozen civilians. The purported airstrike in northern Iraq struck the women’s section of a Shiite mosque on Friday in the town of Daquq amid a large ISIS assault on the nearby city of Kirkuk.
