Kenya's two rival political parties set their sights on parliament Monday, one day before a showdown that will decide who becomes speaker of the East African nation's national assembly. In Nairobi, children in blue uniforms trooped through traffic jams back to school, a sign of normalcy that belies the deep political and ethnic tensions that have battered the country since a disputed December 27 vote. At least 575 people have died in the violence, according to the Kenyan Red Cross. Opposition leader Raila Odinga accuses President Mwai Kibaki of stealing the election, which has been mired in so much controversy even the head of the country's electoral commission has said he does not know who won. Odinga's party has called for more protests Wednesday through Friday in an effort to step up pressure on Kibaki. Violent street protests nationwide trashed cities and burned countless homes to the ground, leaving 250,000 people displaced.
