An apocalyptic scene is unfolding in Mosul, Iraq's second largest city. Large sulfur fires and huge pits of oil are burning. Buildings are booby trapped, hundreds of suicide bombers are on the loose. Hundreds of thousands of people in Mosul may be displaced and many run the risk of being used as human shields as ISIL fighters try to repel Iraqi forces. Those forces are leading the charge to retake Mosul. Colonel John Dorrian, spokesman for Operation Inherent Resolve, discusses the threat, the attack plan the status of Abu Bakr al Baghdadi and U.S. involvement in the fight.
