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, Reuters cited witnesses as saying. 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. Residents in other areas fled in panic as the gangs from rival ethnic groups roamed the streets, according to witnesses. The long-delayed legislative vote, tentatively set for May, is needed to complete a transition to civilian rule after a 2008 military coup, and could open the door to hundreds of millions of dollars in European aid. -- SPA
