Washington: The Capitol building in Washington DC was briefly put on alert Wednesday after a small plane violated air space above the area. The private aircraft briefly entered restricted airspace in the Capitol Hill, but was turned away shortly by military planes, according to TV and wire reports.

As a precaution, the threat level was raised from yellow to orange for the Capitol Building and personnel inside were prepared to evacuate and tourists were asked to stay out of the building. After it was established that there was no imminent threat and the plane left the area, the threat level for Capitol Building was soon returned to yellow, and later returned to green.
