The State Department is failing to adequately protect U.S. diplomats in Beirut, leaving them without necessary counterterrorism training and serving in a decrepit, aged embassy compound that fails to meet security protocols, according to an internal investigation that raises new questions about the Obama administration’s commitment to protecting Americans overseas in the aftermath of the Benghazi tragedy.

In fact, the department did not place Beirut on its latest list of high-threat diplomatic missions even though Lebanon is listed at the “critical” threat level for potential violence with its frequent rocket attacks, spillovers from the Syrian civil war and heavy presence of the terror group Hezbollah, the agency’s inspector general said in a report reviewed by the Washington Guardian.

Beirut was also the site of one of America’s deadliest terror attacks, the 1983 bombing of a Marine barracks that killed more than 240 servicemembers.
