ANDERSON COOPER, CNN ANCHOR: We begin a new segment tonight, "Terror Watch," reports from our correspondents around the globe, trying to help us get a sense of what the terror threat is that we all face. Tonight, the terror watch begins in London, where three men are in custody, suspected of plotting major terrorist attacks in Britain. London's "Sunday Times" is reporting the trio was cooking up a plot to gas London's crowded subway systems. CNN's Jim Boulden is in London with the latest.</s>JIM BOULDEN, CNN CORRESPONDENT (voice-over): London police have confirmed that earlier this week, three men have been charged with terrorism under the Terrorism Act of 2000 for "possession of articles for the preparation, instigation and commission of terrorism acts." These arrests and charges have come after several months of investigations. Now the police are refusing to confirm local news reports that these men may have been planning an attack on the London Underground, the subway system here. And that attack may have come in the form of cyanide. It's important to note that these men were not arrested with any possessions of any cyanide or any bomb making equipment, but of possession of material that may have been used in the Terrorism Act. All three men will appear in court here in London on Monday. And it's believed that the three are of North African origin, and they were arrested on November 9 when the police raided about a half dozen houses in North London. Six people were arrested at that time. Three had been released. And as I say, three men have been charged. Now under the strict press laws here in the U.K., we're not able to say much more at this time, but we can say that it was several months of investigations into this Terrorism Act. And it was decided these men better be picked up before anything else might have happened. Jim Boulden, CNN, London.</s>COOPER: It is obviously a developing story that we will continue to follow.
