WASHINGTON (AP) - A quart-sized container of homemade explosives is cheap, deadly and difficult to detect - and that is exactly why the type of chemical bomb feared to be at the heart of an ongoing terror investigation worries law enforcement so much.
As FBI and New York police counterterrorism agents investigate a Denver man who authorities say received al-Qaida explosives training and recently traveled to New York, law enforcement officials around the nation have been advised to be on the lookout for any signs of bombs built with hydrogen peroxide.
That type of weapon killed 52 people in the London transit system four years ago. During the morning rush hour of July 7, 2005, three men carried backpacks that exploded within 50 seconds of each other on three London Underground trains. A fourth bomb exploded on a bus nearly an hour later.
The same chemical components were allegedly at the heart of a failed plot to blow up commercial passenger jets leaving England for America. That plot was based, according to court evidence, on amounts of chemicals small enough to fit into soda or water bottles.
Now, according to law enforcement officials speaking on condition of anonymity because they were not authorized to discuss the investigation, authorities are concernedthat 24-year-old Afghan immigrant Najibullah Zazi may have been trying to put together a plot to detonate similar devices in backpacks, possibly on crowded commuter trains in New York. Zazi has been charged only with lying to authorities, and has told reporters he has nothing to do with terrorism.
