Libyan officials say the US ambassador and three other Americans have been killed in an attack on the US consulate in the eastern city of Benghazi by protesters angry over a film that ridiculed Islam's Prophet Muhammad.
The officials say Ambassador Chris Stevens was killed Tuesday night when he and a group of embassy employees went to the consulate to try to evacuate staff. The protesters were firing gunshots and rocket propelled grenades.
All of the officials - three in all - hold senior security positions in Benghazi.
They are deputy interior minister for eastern Libya Wanis al-Sharaf; Benghazi security chief Abdel-Basit Haroun; and Benghazi city council and security official Ahmed Bousinia.
