Members of the presidential guard fire into the air to disperse a crowd of opposition UDPS supporters outside N’Djili airport in Democratic Republic of Congo’s capital Kinshasa November 26, 2011. Police in Congo blocked President Joseph Kabila’s main rival at an airport in Kinshasa on Saturday to stop him staging an election rally after at least two died in violence across the central African state’s capital city. Two days before presidential and parliamentary elections, rival factions hurled rocks at each other and gunfire was heard across town.REUTERS/Finbarr O’Reilly (DEMOCRATIC REPUBLIC OF CONGO – Tags: POLITICS CIVIL UNREST)
