At least 13 people are dead and several others were wounded after a shooter opened fire at the Washington Navy Yard on Monday, police said, spreading fear and chaos across the region as authorities sought to contain the panic.

The incident, in which the death toll rose almost hourly, represents the single worst loss of life in the District since an airliner plunged into the Potomac River in 1982, killing 78.

D.C. Police Chief Cathy L. Lanier and Mayor Vincent C. Gray announced the mounting number of casualties in a series of news conferences. The suspected shooter, identified by the FBI as Aaron Alexis, 34, from Fort Worth, Texas, is among the 13 dead. Alexis was a military contractor, one official said.

But even hours after the rampage began, it was still unclear whether the shooting was the act of a lone gunman, or if other shooters were involved. Lanier initially said authorities were looking for two more potential shooters dressed in military style clothing. But shortly after she announced a detailed description of two suspects, city officials said one had been located and cleared.

Gray said no motive is known yet. He said there is no reason to believe it was an act of terrorism, though he added that he could not rule it out.

Gray said that in addition to those killed, about a dozen people were hurt. It was not clear whether those people were shot or suffered other injuries, he said.

Lanier described the other possible suspect, who has not been located, as a black man in his 40s with gray sideburns, wearing an olive-drab military-style uniform. He, and the man who was cleared, came under suspicion when they were seen on surveillance videos.
