been swifter than expected. the operation could go on for weeks. tonight, the report from on the ground in northern iraq. first to pentagon reporter, jim miklaszewski. good evening. >> good evening, lester. the latest u.s. air strikes were launched after rebels fired on the refugees. thousands of refugees remain trapped on top of the mountains. u.s. officials tell nbc news american warplanes and a drone launched four air strikes against rebel forces in the sinjar mountains, taking out three armor ed planes. earlier today, the president made it clear the u.s. would not stand by and let that happen. >> the american aircraft are positioned to strike isil terrorists around the mountains to break the siege and rescue those trapped there. >> reporter: this, after

american warplanes and a drone took out three isis targets yesterday outside of erbil. clearly shaken by those air strikes, the rebels were seen removing their trademark isis black flags from their vehicles, which made them easy targets. >> so far, the strikes have successfully destroyed arms they could have use zed against them. >> reporter: it appears to be a glancing blow. isis released a video today from mosul showing off military equipment seized from iraqis and planting their flag on the biggest prize yet, the mosul dam critical to iraq's infrastructure. at the same time, three u.s. military cargo planes made the secondary drop of tons of food and thousands of gallons of water to yazidi refugees. surrounded by isis fighters, many are dying of thirst and starvation.

for the first time, president obama talked about creating a safe corridor to provide the refugees an escape route off the mountain. a complex and dangerous operation, which would require military boots on the ground. >> fundamentally, this is not going to change the tide in iraq. it will take much more on the part of iraqis and likely the u.s. to do that and push isis back. >> reporter: whatever the strategy, the president stressed the iraqis must take the lead. >> we can help, we can advise, but we can't do it for them. >> reporter: it's clear president obama has carved out a major role for the u.s. and its military in the way forward. lester? >> jim miklaszewski, thanks. tonight, we are on the ground in iraq. we are learning more about the stranded members of the religious minorities. horrific stories are emerging. we'll get more from erbil.
