WATCH---------> U.S. Airstrikes Take Out ISIS Militants, Vehicles In Fallujah

Hundreds of ISIS militants were killed in a series of U.S. and Iraqi airstrikes Wednesday that targeted two large vehicle convoys fleeing the western Iraqi cities of Fallujah and Ramadi, according to U.S. officials.

Officials estimate that at least 250 ISIS fighters were killed in the airstrikes outside of Fallujah and that at least 175 vehicles were destroyed in the airstrikes outside both of the cities.

Over the last two days, U.S. and Iraqi aircraft targeted the large convoys of ISIS fighters as they fled both cities, said Col. Chris Garver, the spokesman for Operation Inherent Resolve. (ABC News)
