Washington: The U.S. ambassador to Libya has been killed after being attacked by militiamen who stormed the American consulate in the eastern city of Benghazi, BBC reported Wednesday.
The State Department has confirmed the death of an official but it has not named him.
Xinhua quoted Al Jazeera TV as saying that hundreds of protesters broke into the consulate building.
The ambassador, who was on a short trip to Benghazi, apparently died of suffocation as a result of smoke inhalation after the mob set fire at the scene.
Libya's Supreme Security Committee spokesman Abdel-Monem Al-Hurr said: "One American staff member has died and a number have been injured in the clashes."
U.S. Secretary of State Hillary Clinton confirmed "a staff member" died.
In Cairo, several thousands of Egyptians protested in front of the U.S. embassy against the same movie, allegedly sponsored by Americans but not by the U.S. government or Hollywood companies.
