The White House was locked down and the U.S. Capitol and its office buildings were briefly evacuated Tuesday amid concerns about a small aircraft that violated restricted airspace in the area.
The evacuations were ordered as a precaution and lasted about half an hour.
According to WJLA, however, it wasn't an airplane but rather a flock of birds that put the nation's capital on alert.
The jets that were sent to intercept what was first thought of as a plane, never found an aircraft.
The U.S. Secret Service said personnel at the White House were told to remain in place. That precaution was later lifted as well.
Capitol Police sent a notification of a potential threat shortly after 8:30 a.m., and the evacuations were ordered. People were allowed back in after about 30 minutes.
Jet aircraft were scrambled in response to the incident.
