BLITZER: Red-hot clouds of fire. Look at this. Exploding into the sky, raging for hours and hours. Tonight it's still a hazardous situation at the scene of that train derailment in West Virginia amid a massive oil spill. CNN's Rene Marsh is in THE SITUATION ROOM with an update of what's going on. Very disturbing.</s>RENE MARSH, CNN CORRESPONDENT: It is. And those images are hard to believe that only one person injured. I just got off the phone with the West Virginia emergency management team. We do know that they are periodically testing the water in this area. They want to make sure that it's not contaminated. We can tell that you three tests have been done and they were able to come to the conclusion that at this point they do not believe any oil was able to make its way into the water supply, which is also a source of drinking water for people in this area. We can tell you, more than 100 people displaced, close to 800 people without power because that massive fire that you're looking at there, it burned power lines. Of course, this all stems from Monday's derailment of a CSX train that was hauling crude oil from North Dakota to Virginia. It derailed and then ended in that fiery explosion. There was one man who saw it all unfold before his very eyes. Take a listen.</s>ALEX FANDOR, WITNESS: We're standing out on the river bank when we saw all train explode, or the car explode and it shot up a mushroom cloud about as high as the plume is now, like that.</s>MARSH: It's just massive, massive flames there. And we should point out, at this hour, the fire is still burning. They don't believe that they will get it out until around midnight. So, that's still a situation they are dealing with. We know that, of course, this highlights just the safety concern to transporting the highly explosive crude oil throughout these neighborhoods.</s>BLITZER: It's very worrisome. Thanks very much for that, Rene. Just ahead, a major new offensive by ISIS is unfolding right now.
