WASHINGTON (May 11) - U.S. authorities gave the all clear on Wednesday after evacuating the White House and Congress in response to a feared threat from an unidentified aircraft, officials said.
The Secret Service gave the "all clear" within minutes of the scare and allowed staff to return to their offices.
An official of the Homeland Security Department identified the plane as a Cessna, which is a light aircraft. Fighter jets had scrambled over the American capital in the alert.
Sarah Little, an aide to Sen. Pat Roberts, R-Kan. said the order to evacuate came over the special pager devices that every congressional office has.
''They said to head South because there is an imminent aircraft threat,'' Little said.
Reporters in the White House were told to move to a more secure location.
President Bush was not at the White House at the time.
A guard in the West Wing of the White House shouted at reporters, ''Go down into the basement.''
''Leave, run,'' security officers shouted to staff and reporters at the Capitol.
''This is not a drill,'' guards shouted as they moved people away from the building.
Shortly after noon, officers rushed through the Supreme Court building and told staff to get into the basement. At the Treasury Department, people were moved across the street.
