Nightmare: al Qaeda dirty bomb threat

Authorities have a specific threat of an al Qaeda dirty bomb plot for New York or Washington. This information comes from an informant in Pakistan who reportedly has never been wrong. Let's hope this is his first error.

NEW YORK (CBSNewYork) — Just two days before the 10th anniversary, New York City is on high alert.
Federal and local authorities have beefed up security after receiving intelligence about a credible threat. The alleged plot by al Qaeda involves detonating car bombs on bridges and in tunnels in New York and Washington D.C. to coincide with the anniversary of 9/11.

Chopper 2 HD got a look at the NYPD in action on Friday — police cruisers and orange cones marked one checkpoint on the George Washington Bridge. On the West Side Highway, at one of the many checkpoints, police were stopping drivers and searching vehicles, specifically vans and trucks. There is also a threat to bridges and tunnels.

Security was equally tight at Penn Station, where armed guards were keeping watch over travelers as Transportation Security Administration agents performed random bag checks, swiping packs for gunpowder.
The crossroads of the world came to a grinding halt at various times Friday because for police Times Square has become the ground zero of the latest terror threat. Sources told CBS 2’s Marcia Kramer that another attempt to explode a bomb there is a key concern, and the intelligence suggests it could be a dirty bomb.
