Developing: Shooting At U.S. Navy Yard In Washington, D.C.

Initially, there was word that only a few people had been injured. Among those hurt, according to reports from emergency personnel, was a police officer who was struck at least twice.

But at 10:04 a.m. ET, the Navy added that there had been “reports of fatalities.” It wasn’t clear whether the Navy was reporting that there had been deaths, or that it was just acknowledging that there had been such reports.

The area around the Navy Yard in southeast Washington was quickly filled with police and emergency personnel.
