Pennsylvania Avenue remains closed near White House

A week after two men set off bombs at the finish line of the Boston Marathon, one of Washington's security responses is still ongoing, according to the Washington City Paper.

The City Paper says that the pedestrian portion of Pennsylvania Avenue in front of the White House remains taped off and inaccessible to the public. The area directly in front of the mansion was shut down almost immediately after last Monday's bombing.

A Secret Service official would only tell the City Paper that the portion of Pennsylvania Avenue remains closed and did not know when it would reopen.

The District and MPD officials have been under a heightened state of alert since last Monday's bombings, which killed three people and injured more than 170.

D.C. Police Chief Cathy Lanier has said in statements that the city continues to monitor developments both in the city and around the country and reacts to them appropriately.
