Police have fired tear gas on hundreds of youth as they gathered in a slum area in day two protest. Four demonstrators have died in riots in the town, on the shore of Lake Victoria, some 350km west of the capital Nairobi a day after. Violent protests blew up after Shem Onyango Kwega, a candidate for a parliamentary seat in Kisumu in general elections due in March, was killed by unidentified armed men on Monday while driving in town. Kwega, the local branch chairperson of Prime Minister Raila Odinga's Orange Democratic Movement (ODM), was shot in the head and later passed out at the hospital while his wife was seriously wounded and was taken to hospital. Youths burnt down tyres along a road in Kisumu, Kenya during riots. The murder was at first attributed to thug, but a political motive was not immediately ruled out.
