Residents of another main eastern city, Darna, have also begun to stand up against Ansar al-Shariah and other militias.
The anti-militia fervor in Darna is notable because the city, in the mountains along the Mediterranean coast north of Benghazi, has long had a reputation as a stronghold for Islamic extremists. During the Gadhafi era, it was the hotbed of a deadly Islamist insurgency against his regime. A significant number of the Libyan jihadists who travelled to Afghanistan and Iraq during recent wars came from Darna. During the revolt against him last year, Gadhafi's regime warned that Darna would declare itself an Islamic Emirate and ally itself with al-Qaida.
But now, the residents are lashing out against Ansar al-Shariah, the main Islamic extremist group in the city.
"The killing of the ambassador blew up the situation. It was disastrous," said Ayoub al-Shedwi, a young bearded Muslim preacher in Darna who says he has received multiple death threats because has spoken out against militias on a radio show he hosts. "We felt that the revolution is going in vain."
