Protesters shout slogans during a demonstration against security forces seeking to arrest Tunisian Salafist leader Saif-Allah Benahssine over clashes at the U.S. Embassy last week, at the al-Fatah mosque in Tunis September 17, 2012. Benahssine, leader of the Tunisian branch of the hardline Islamist Ansar al-Sharia, on Monday escaped from the mosque that had been surrounded by security forces seeking to arrest him over clashes at the U.S. Embassy last week during protests against an anti-Islam film, a Reuters witness said. He slipped away after hundreds of his followers stormed out of al-Fatah mosque, some wielding sticks and creating panic among pedestrians. The flag reads, “There is no god but Allah and Mohammad is the prophet”. REUTERS/Zoubeir Souissi (TUNISIA – Tags: POLITICS CIVIL UNREST RELIGION) – RTR3835N
