A woman was shot by CIA security Thursday morning after she drove up to a gate at the agency's headquarters, and failed to stop, sources said. The woman was taken to a medical facility with what law enforcement officials believed was a non-fatal gunshot wound to the upper body.

A security incident outside CIA headquarters early Thursday led to a shooting, authorities said.

The source, speaking on condition of anonymity, said a check of public records showed the suspect, identified as a young U.S. citizen, had a history of driving under the influence.
