In a reversal, the National Park Service removed fencing around Dupont Circle Park and opened it to the public. Before sundown, two people were stabbed and one was shot.

City authorities canceled an initial request to block off the site, an L.G.B.T.Q. gathering spot in Washington, D.C. But the National Park Service opted to close it.

A shooting and a double stabbing are under investigation in the Dupont Circle neighborhood amid WorldPride DC festivities in the area. The violence follows a week of back-and-forth about whether Dupont Circle Park would remain open for this weekend’s Pride events.
