The U.S. Coast Guard fired at a suspicious boat in the Potomac River in Washington, D.C., near the Pentagon amid high security during Sept. 11 memorial ceremonies at the Defense Department headquarters, U.S. media reported on Friday.
President Barack Obama and Secretary of Defense Robert Gates had been attending a ceremony at the Pentagon, south of the city on the Virginia side of the river.
CNN said the Coast Guard fired about 10 rounds at the boat, which they described as a recreational vessel, after it entered a temporarily restricted zone in the Potomac, which separates Washington, D.C., from suburban Virginia where the Pentagon is located.
Traffic was moving freely across bridges and did not appear affected by the incident.
