WASHINGTON, May 11 (Xinhuanet) -- The US Capitol and White House were evacuated briefly Wednesday after a small plane entered restricted airspace over the capital.

    People at several other government buildings, including the Treasury Department and the Supreme Court, were also ordered to evacuate.

    But within minutes the Secret Service gave the "all clear" and allowed staff to return to their offices.

    The scare was caused by a small plane that entered the securityzone over Washington. A fighter aircraft intercepted the plane, which was identified as a Cessna.

    President George W. Bush was not at the White House during the evacuation, officials said.

    On April 27, Bush went to an underground shelter and Vice President Dick Cheney was taken to a secure location after security officials received a false alarm that an unidentified aircraft had entered the restricted space near the White House.

    It was quickly learned that it was a false alarm and that all was clear within minutes. Enditem
