MOMBASA, Kenya — Four people were killed in renewed violence between rival tribes in Kenya's coastal Tana Delta region on Tuesday despite a dusk-to-dawn curfew imposed by the government, the Red Cross said. Houses had been torched and many people were fleeing the clashes, the Red Cross said in a statement. More than 100 people have been shot, hacked to death and burnt alive during three weeks of violence rooted in disputes over land and water between the Pokomo and Orma. Hundreds of attackers had regrouped on Tuesday and launched new attacks, the Red Cross said. — Reuters
