i want to take you back now to the breaking news coming to us out of los angeles. look at these pictures, a building explosion occurred there this morning due to a natural gas explosion. these coming in to us from our affiliate, knbc. we understand this is a welding operation. two people, so far that we know of, were hurled from that building, thrown out and wedged underneath cars in the parking lot out there. we know that they have been taken off to the hospital. there are now search crew dogs that are going in there to search for potentially other victims, as we understand it, the splintered wreckage there makes it too difficult for the fire and rescue teams that were on the scene to extinguish the flames there. too dangerous for them to go inside. they are using trained search dogs to look for potential other victims there. again, this happened about 9:15 eastern, 6:15 pacific time. what we understand a natural gas explosion ripped the front of that building off causing it to collap
