Fire breaks out in a store during clashes between rival gangs in Marche Madina, in Conakry March 1, 2013. Rival gangs fought with knives and truncheons in Guinea's crumbling seaside capital on Friday as ethnic tensions worsened ahead of an election in the unstable West African nation, witnesses said. Security forces in full anti-riot gear piled into the backs of pick-up trucks and deployed across Conakry to separate the fighters as President Alpha Conde's government appealed for calm.
