TRIPOLI, Libya (AP) -- Libyan officials say the U.S. ambassador and three other Americans have been killed in an attack on the U.S. 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.
President Obama condemned the attack early Wednesday.
All of the officials reporting the deaths -- 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.
Protesters also scaled the walls of the U.S. Embassy in Cairo, and replaced the American flag with an Islamic banner.
Secretary of State Hillary Rodham Clinton says she is concerned that the protests will spread to other U.S. diplomatic facilities in other countries.
