WHITFIELD: The U.S.-led anti-ISIS coalition confirms it is investigating allegations that hundreds of civilians have been killed in recent air strikes. CNN's Barbara Starr has details.</s>BARBARA STARR, CNN PENTAGON CORRESPONDENT: One of the most widespread allegation that's U.S. aircraft strikes in Mosul, Iraq, may have caused up to 200 or more civilian deaths. What the U.S. military is saying is they are aware of these allegations from social media, from activist groups, from Iraqis, and they are looking into it. This was an area in west Mosul, heavily populated. There were a number of air strikes over recent days. There had been social media reports and videos emerging of civilians killed in the area. The U.S. military says it was bombing in the area but it trying to get fidelity, did it bomb these buildings, were civilian casualties caused. They're looking at a recent strike near a mosque near Idlib, Syria. Civilians said to be killed there. They are looking into yet another case of a school building bombed north of Raqqa, Syria. More than 30 civilians were seeking shelter in that building. It is said they are looking into those allegations as well. No final answer on any of these, but a number of investigations now underway. And the U.S. military insists, if it is said to be found responsible, it will take that responsibility.
