ISIS attacks Iraqi city of Kirkuk as Mosul offensive intensifies

The United Nations said Friday it is "gravely worried" that ISIS has taken 550 families from villages around Mosul, Iraq's second-largest city, and is using them as "human shields" as Iraqi and Kurdish forces battle the terror group for control of the city. Two hundred families from Samalia village and 350 families from Najafia were forced out Monday and taken to Mosul in what appears to be "an apparent policy by ISIS to prevent civilians escaping," Ravina Shamdasani, deputy spokeswoman for the UN Human Rights Office, told CNN.
