CNN’s Walsh: UN Has Warned ‘550 Families May Be Being Used as Human Shields by ISIS’

"That unexpected attack against Kirkuk really a bit to throw the Peshmerga who control that oil rich city on their back feet. Continuing fighting: 30 ISIS militants involved, seven of them dead we know so far. They’ve been attacking security headquarters. I should also tell you now the United Nations to give you a snapshot of how brutal this is have just warned that 550 families may be being used as human shields by ISIS. Some of them in fact forced to walk on foot from the village where they live a matter of days ago. The front lines here very violent. ISIS not yielding any territory unless they absolutely have to."
