An administration official says the chief of the State Department’s security service, one of his deputies and an official from the agency’s Middle East bureau have resigned after a damning report that found systematic management failures responsible for a lack of security at the U.S. diplomatic mission in Benghazi, Libya.

The official said Eric Boswell, the assistant secretary of state for diplomatic security, and Charlene Lamb, the deputy assistant secretary responsible for embassy security, stepped down under pressure after the release of the report. The third official worked for the Bureau of Near East Affairs, but wasn’t immediately identified, the official said, speaking on condition of anonymity because he wasn’t authorized to discuss personnel matters publicly.
