(MCT) — WASHINGTON — The State Department was guilty of “systematic failures” in security that made the deadly Sept. 11 terrorist attacks on the U.S. mission in Libya possible, a high-level investigative panel concluded in an unflinching examination made public late Tuesday.

The panel faulted the department for ignoring requests from U.S. diplomats in Tripoli for security assistance and for relying on ill-prepared local militias and inadequate equipment to protect the mission in Benghazi. It found that two key bureaus failed to properly coordinate their security planning, and it pointed to a failure in leadership by officials at several levels.
