Multiple news agencies are reporting that the U.S. Ambassador to Libya and three others were killed in a rocket attack on their vehicle (although reports as to where he was at the time conflict).  The State Department has not confirmed as of this writing.  (Update – The White House has confirmed.)

The U.S. ambassador to Libya and three other embassy staff were killed in a rocket attack on their car, a Libyan official said, as they were rushed from a consular building stormed by militants denouncing a U.S.-made film insulting the Prophet Mohammad….

The Libyan official said the ambassador, Christopher Stevens, was being driven from the consulate building to a safer location when gunmen opened fire.

“The American ambassador and three staff members were killed when gunmen fired rockets at them,” the official in Benghazi told Reuters.

Via Al Ahram English:

Al-Jazeera’s Suleiman Idrissi in Benghazi reported that the ambassador had been paying a short visit to the Eastern city, when the US building came under attack.

Security sources told the pan-Arab news agency that Stevens died of suffocation. The bodies of the dead were transported to the Benghazi international airport, to be flown to Tripoli and then onwards to a major US airbase in Germany, Al Jazeera added…..

Stevens had served as an envoy to Libya’s National Transitional Council during the Libyan uprising last year. The last US ambassador to be killed on duty was Adolph Dubs who died in an exchange of fire during a kidnapping attempt in Afghanistan in 1979.

Updates:

A photo is circulating of what purports to show Libyan protesters carrying the body of the Ambassador.  It is unconfirmed.
