At least ten shot at Washington Navy Yard by gunman armed with AR15 rifle - and he's still on the loose

Police have reported that three gunmen, including one wearing camouflage, have shot dead four people - including two police officers - and injured another eight this morning at the Washington Naval Yard. Police have said that at least one of the gunmen, who are said to be armed with AR-15 rifles, has been taken 'down', however it is not clear if he has been arrested or shot. Two gunmen remain at large and police have said that one of the shooters has been pinned down between the third and fourth floors in a room on the grounds of the naval yard, although this has not been confirmed. One of the gunmen is not accounted for and hundreds of police, SWAT and FBI rapid response units have descended on the nation's capital to deal with the situation. In addition the spokesman added that all of the people wounded are in critical condition and have been rushed to nearby hospitals.
