No injuries were reported at the U.S. Navy Yard in Washington on Thursday, a spokesman for the Washington D.C. Fire Department said, after the facility was placed on lockdown following reports of a possible shooter.
A shooter had not been found as police swarmed the Navy Yard, according to a local CBS radio station, amid heightened security concerns ahead of the U.S. July Fourth holiday weekend.
No further details were available about the incident at the Navy Yard, which is a mile south of the U.S. Capitol and 3 miles from the White House.
