A popular Sufi cleric was assassinated in Derna; a group called Vanguards Of The Caliphate claimed the attack. Derna, which like Benghazi has seen a number of political assassinations this year, is a known stronghold of Ansar al Sharia. A commander of the SSC militia was murdered yesterday in Tripoli. Prime Minister Zeidan’s press office denied reports that protesters at the Benghazi airport prevented him on Sept. 21 from entering the city. An armed gang in Benghazi shot and killed a businessman that same day.
