Clashes between rival tribes in the Kenyan capital killed at least three people on Sunday in a fresh flare-up of ethnically-motivated violence after President Mwai Kibaki's disputed re-election this month, witnesses said.

All of the bodies bore scars of machete attacks.

"I saw three people dead, killed by pangas (machetes), slashed on the head, cuts on the back and a hand chopped off," Samuel Oduor, 22, a freelance cameraman, said. He had footage of one of the bodies but police had collected the others, he said.
