Three people have died in violence in Kenya, two days after the killing of a radical Muslim cleric.
Two Kenyan police officers and a civilian died when rioters hurled a grenade at officers in the port city of Mombasa. Youths had fired at police with machine guns just before throwing the grenade into a police truck, according to police.
The riots broke out yesterday after the shooting dead of Aboud Rogo Mohammed, who was accused by the US of helping al-Qaeda-linked Islamist militants in Somalia.
Gunmen sprayed Mr Rogo's car with bullets in an attack many Muslims in Mombasa blamed on police, who denied involvement.
Police said at least 16 police officers were injured in the grenade attack in Kisauni, a predominantly Muslim area.
They blamed youths for setting fire to two churches and barricading roads with burning tyres as the riots spread to the outskirts of Kenya's second-biggest city, a tourist hub and major Indian Ocean port.
The city's main streets, usually thronged with shoppers and foreign tourists, were deserted and some shops were shuttered.
Shopkeepers reported looting in some areas of the city and police said rioters had looted and set fire to a bank.
One person was killed in riots yesterday when protesters set fire to several churches, stoking fears that the unrest may become more sectarian.
The United States and Kenya had both accused Mr Rogo of helping al Shabaab, Somalia's Islamist rebel group.
The al-Qaeda-linked militant group has urged Kenyan Muslims to protect their religion at all costs and boycott next year's presidential election.
It condemned what it called a "witch-hunt" against Muslims by the Kenyan authorities.
