The New York Times reports one man was killed and a second was injured on Monday when their car tried to crash through a gate at the National Security Agency in suburban Maryland, and security personnel opened fire, said a spokesman at Fort Meade United States Army Base. A law enforcement official said both men were dressed as women, and identified the survivor as Kevin Fleming of nearby Baltimore. They were driving a Ford Escape S.U.V. that had been reported stolen. “The incident has been contained and is under investigation,” said Col. Brian Foley, Fort Meade garrison commander. “The residents, service members and civilian employees on the installation are safe. We continue to remain vigilant at all of our access control points.” An F.B.I, spokeswoman, Amy Thoreson, confirmed that “a shooting incident” had taken place at an N.S.A. gate just off Interstate 295, the Baltimore-Washington Parkway. “We do not believe it is related to terrorism,” she said.
