Two people tried to ram the main gate to enter the headquarters of the National Security Agency at Fort Meade, Maryland on Monday, according to a federal law enforcement official briefed on the investigation. An NSA police officer shot one of the people dead dead and seriously injured the second.
A law enforcement official had previously reported that both of the people involved were men. Aerial shots show two vehicles at an intersection that appear to be damaged.
The FBI said Monday morning that it was conducting an investigation with NSA police and other law enforcement agencies, and interviewing witnesses on the scene. The incident took place near one of the gates to the complex, far from the main buildings. The FBI said they did not think terrorism was related to the incident.
"We are working with the US Attorney's Office in Maryland to determine if federal charges are warranted," the FBI said in a statement.
White House Principal Deputy Press Secretary Eric Schultz said President Barack Obama had been briefed on the incident this morning.
