BLITZER: A freight train that derailed near Baltimore disrupts an important terror trial in Guantanamo Bay. Lisa Sylvester is monitoring that and some of the other top stories in THE SITUATION ROOM right now. What do you have, Lisa?</s>LISA SYLVESTER, CNN CORRESPONDENT: Wolf, yesterday's accident damaged fiber optic lines and knocked out internet service as far away as Cuba. That delayed a pre-trial hearing for accused September 11th master mind Khalid Sheikh Mohammed and four others. We are told that service is back up now. Two college students were killed when the coal train derailed. Police say the teens were sitting on a bridge when 21 cars tumbled off the tracks. He plays a crime fighting agent on TV. L.L. Cool J helped take down a real bad guy who tried to break into his Los Angeles area home. The rapper and actor heard a noise early this morning and confronted the-would be burglar. Police say L.L. Cool J was holding the guy when they arrived. L.L. whose real name happens to be James Todd Smith, he is OK. But the suspect, the other guy, well, he's got a few bruises. I think that's a lesson learned, Wolf. Don't take on L.L. Cool J. He's a pretty big guy.</s>BLITZER: Wouldn't even think about it. Wouldn't even come close to doing that. All right, thanks very much, Lisa. Once again, we're keeping a close eye on that Tropical Storm Isaac right now. It's moving through the Caribbean. We're going to have a full report on where it could be heading. That's coming up the top of the hour. And what's fuelling the Mars rover? We have the answer and it may surprise you.
