american military advisers just arrived in iraq. there are 10,000 militant fighters in the country and across the border in syria. that may not sound like a lot but they're doing a lot of damage. isis continuing a deadly march through iraq taking over towns and cities. these are new pictures posted on a twitter account associated with isis. they allegedly are taken in the northern province of nineveh. we haven't been able to confirm the authenticity. these are the pictures they're posting, with launching rocket, men lined up before they were shot and executed. as you can see from behind and much closer to baghdad, the video that we're going to show you here posted on youtube. again, we haven't been able to independently confirm this either, but this is what it supposedly shows, iraqi security forces allegedly fighting isis rebels in fallujah. displaying rebels kill katie on the hood of a humvee.
