WASHINGTON - U.S. officials said yesterday that they were investigating a detailed al Qaeda car-bomb plot aimed at bridges or tunnels in New York City or Washington to coincide with the 10th anniversary of the 9/11 attacks, the first tip of an "active plot" targeting that date.
The Homeland Security Department said the threat was credible and specific but unconfirmed. The nation's terror-alert level has not changed, but change was under consideration last night.
Law-enforcement officials were investigating three people who recently entered the U.S. The threat came in late Wednesday and was the first tip that the U.S. intelligence community has received about an "active plot" targeting the anniversary, officials said.
