Files taken from Osama Bin Laden's secret compound have already resulted in key information -- al-Qaeda wanted to pull off a U.S. train attack on the upcoming 10th anniversary of 9/11. However, terrorism analysts are quick to point out that while this is something al-Qaeda wanted, there is no evidence that plans were actually put into place.
The Associated Press reports Homeland Security sent an intelligence warning to law enforcement agencies around the country on Thursday marked for "official use only." It said that as of February 2010, al-Qaeda was considering tampering with an unspecified U.S. rail track so a train would fall off the track right before a valley or a bridge.
The warning said:
While it is clear there was some level of planning, we have no recent information to indicate an active ongoing plot to target transportation and no information on possible locations or specific targets.
"We want to stress that this alleged al-Qaeda plotting is based on initial reporting, which is often misleading or inaccurate and subject to change," Homeland spokesman Matt Chandler said. He added that the government has no plans to issue an official terror alert.
Navy Seals recovered computers, DVDs and documents from Bin Laden's hideout. Intelligence analysts continue to sift though it for information about plots and terror connections.
Terrorists have targeted train systems before. Police foiled a plot to blow up New York City subways in 2009, but terrorists were successful in London, Spain and India in recent years.
