morning after this unbelievably devastating explosion just outside of san francisco. a state of emergency in san bruno this morning. a powerful gas line explosion triggering a deadly, destructive inferno. dozens of homes destroyed. the heat hot enough to crack car windshields from blocks away and to melt taillights as people were seen running for their lives out of the neighborhood. we're getting the latest information on it this morning friday, september 10th. glad you're with us. i'm kiran chetry. >> i'm john roberts. thanks for joining us. lots to tell you including a brand new twist overnight in the koran burning that was planned for tomorrow on 9/11 in gainesville, florida. will it happen? >> this morning we're hearing from the florida pastor who called it off yesterday and then seemed to indicate there was a possibility he'd go ahead with it. live report from john zarrella in gainesville in just a few minutes and we're going to be talking to the florida imam as well that may have helped broker this decision to not go ahead
