Homeland Security spokesman Matt Chandler issued a statement Thursday that the department has no information on "any imminent terrorist threat to the U.S. rail sector, but wanted to make our partners aware of the alleged plotting; it is unclear if any further planning has been conducted since February of last year."
"We want to stress that this alleged al-Qaida plotting is based on initial reporting, which is often misleading or inaccurate and subject to change," Chandler said.
He said the department and its partners since Sunday have reviewed protective measures for all potential terrorist targets, including critical infrastructure and transportation systems across the country and deployed additional officers to non-secured areas at airports.
The assault team that raided bin Laden's compound took more than 100 storage devices and 10 hard drives, along with five computers and five cell phones. The information is being analyzed and unencrypted now.
