ISIS Used Men, Boys As Human Shields Leaving 284 Dead - CNN

ISIS rounded up and killed 284 men and boys as Iraqi-led coalition forces closed in on Mosul, the terror group's last major stronghold in Iraq, an Iraqi intelligence source told CNN.

Those killed Thursday and Friday were used as human shields against attacks forcing ISIS out of southern parts of Mosul.

ISIS dumped the corpses in a mass grave at the defunct College of Agriculture in northern Mosul, the intelligence source said.

The victims including children were all shot, said the source, who asked for anonymity because he is not authorized to speak to the media. CNN is however yet to independently confirm the killings.
