(ajz) Kenyan troops have moved into the town of Naivasha in the western Rift Valley province in an attempt to quell tribal fighting. But hundreds of people from rival tribes, wielding machetes, clubs and rocks, confronted each other on Monday on a main Naivasha road. Katee Mwanza, the district commissioner, said at least 22 people were killed in the Naivasha area in ethnic clashes over the past two days. Police said a least five of those were burned to death in their homes. Naivasha, a major commercial centre, is known as Kenya's flower capital. Kenya has been swept by ethnic violence triggered by a disputed presidential poll last month. The death toll from a month's violence now stands at nearly 800, while at least 260,000 have been displaced since December 27. In the normally peaceful Rift Valley town of Nakuru, a mortuary worker said on Monday that 64 corpses were lying in the morgue, all victims of the past four days of ethnic fighting.
