Kenyan police Wednesday fired tear gas at protesters who took to the streets in defiance of a government warning after earlier demonstrations turned violent with more than a dozen people killed. The opposition has vowed to stage three straight days of protests against President William Ruto’s government, alarming the international community which has joined calls for a political solution to the crisis. Schools and shops were closed in Nairobi and other cities, and many frustrated Kenyans urged the two sides to bridge the impasse.
