has happened. >> courtney, do we have any idea about civilians who could have been in that area at that time? >> we don't know yet. the u.s. military doesn't have their battle damage assessment, so we don't even know how many isis fighters maify have been killed in this strike. they did say it was a rather remote area. it was not surrounded by a village or any kind of civilian area. so they're hopeful -- they always take as many measures as possible to try to minimize any civilian impact, casualties or damage. they're hoping in this case there were not any, but we don't know for sure yet. >> courtney, the pentagon, the d.o.d. is being questioned at least a little bit by folks who say civilian casualties are up in the recent months, that some sort of policy seems to have changed. can you flush that out a little bit for us? >> that's been highlighted recently last month. on may 17 a large strike in mosul.
