FILE – In this Sept. 21, 2012 file photo, Libyan followers of Ansar al-Shariah Brigades and other Islamic militias, hold a demonstration against a film and a cartoon denigrating the Prophet Muhammad in Benghazi, Libya. On Friday, Oct. 31, 2014, bearded militants gathered at a stage strung with colorful lights in Darna, a Mediterranean coastal city long notorious as Libya’s center for jihadi radicals. With a roaring chant, they pledged their allegiance to the leader of the Islamic State group. Many of Darna’s militants joined, though some didn’t. Part of Ansar al-Shariah, one of the country’s most powerful Islamic factions, joined while another part rejected it. (AP Photo/Mohammad Hannon, File)
