Police respond to "active" gunmen at US Navy base in Washington DC - but it was a false alarm

There was a mass shooting at the site in 2013.

POLICE IN THE US have responded to reports that two gunmen were active at the Navy yard in Washington DC, the site of a mass shooting less than two years ago, but it appears to be a false alarm.

DC Fire officials are now saying that there are no injuries at this time. Police are also confirming that there have been no discoveries of guns or evidence of a shooting.

Local TV station WUSA9 reported that they had been told there are two gunmen and Building 197, the sight of the 2013 shooting, was being evacuated.

Streets had been closed around the area and the US Navy had confirmed it was on lockdown.
