Fears that an unidentified aircraft had entered restricted space near the White House today prompted security officials to move President Bush from the Oval Office to an underground shelter.
The scare lasted only a few minutes before officials determined it was a false alarm, White House counselor Dan Bartlett said. Some White House staff members were moved out of the West Wing, and tourists were rushed from the East Wing.
"There was an indication that an aircraft has entered the no-fly zone," White House press secretary Scott McClellan said. "There's an investigation to determine what it really was."
Security officers toting shotguns took up positions around the White House compound.
