Incumbent Declared Winner in Kenya's Disputed Election

As riots shook parts of Nairobi and other major cities, Kibaki told Kenyans to "embrace one another as brothers and sisters" and declared Monday a national holiday.

Soon after, he suspended live television coverage. Stations that had been airing election news almost nonstop suddenly began showing reruns of "ER" and music videos.

The streets were mostly empty. Many people had stocked up on milk, water and food earlier in the day, expecting to remain holed up at home for at least two days of rioting.

At sundown, police helicopters hovered over fires burning across the poorest neighborhoods of Nairobi, where Joshua Mukabwa, a Luo, stood in the smoky haze.

"We are telling all Kikuyus -- we want them all to go back to Central province, and we should have two countries in Kenya," he said.

Among other boozy young Kikuyu and Luo men, tensions seemed to turn to bloodlust.

Walking along an empty street near Kibera, Andrew Ndegwa, who is Kikuyu, said he'd barely escaped a machete-wielding crowd where he lives, and where his wife and baby son remained Sunday night.

"I've just escaped from that place," he said. "They are just going house to house and if they find any Kikuyu, they just start cutting. I'm very afraid."
