Hundreds of people from rival tribes confronted each other on a main road of Kenya's flower capital Monday, hefting machetes, clubs and rocks and retreating only when a handful of police between them fired live bullets into the air. It was unclear whether the officers would be able to keep them apart. Ethnic clashes are continuing to convulse western Kenya, as gangs fought with crude weapons and set homes ablaze in this tourist gateway, pushing the death toll from a month of violence over the country's flawed presidential election to nearly 800, the Associated Press reported.
