WASHINGTON (Reuters) - U.S. Park Police are responding to reports of an active shooter at Navy Yard in Washington, the Washington Post said on Thursday. It provided no other details.
Reuters could not immediately verify the report, which comes amid heightened security concerns ahead of the U.S. Independence Day holiday weekend. Representatives for the Park Police could not be immediately reached.
The Navy Yard, a military installation in the nation's capital, is the site of a 2013 shooting in which a gunman killed 12 people.
