Tunisian protesters shout slogans during a rally outside the Interior Ministry to protest against the assassination of Tunisian opposition leader and outspoken government critic Chokri Belaid (poster) on February 6, 2013, in Tunis. The protesters, who massed on Habib Bourguiba Avenue, epicentre of the 2011 uprising that ousted former dictator Zine El Abidine Ben Ali, pelted the police with bottles and the police responded by firing tear gas, chasing the protesters and beating them with batons.
