get information. >> i was trying to figure out earlier this morning how many people have been killed within syria. the best estimate we have right now are hundreds maybe. >> hundreds maybe, according to witnesses, because we do our best with all the witnesses with he get from eyewitnesses, cross-checking videos with testimony from the ground, 300 plus is what human rights groups are saying in terms of how many people have been killed. what's interesting, carol, is that over the last several weeks, we have received and been able to see on youtube and online video emerge. we have been able to contact people. over the last 24 hours, just a small trickle of video has come out of syria. people are saying that perhaps that is because in an effort to limit communication with the outside world, cutting electricity off from certain cities has worked. people can't charge their phones. they can't charge their laptops. we are not able to get video out. we have only had a few over the last 24 hours versus dozens every day over the last several weeks. hala gorani, many thanks.
