A violent backlash to the killing of a radical Islamic preacher continues in Kenya's coastal city of Mombasa, with running battles between police and protesters.

A police official says officers have teargased rowdy youth on their second day of protests over the killing Monday of Aboud Rogo, who was sanctioned by the U.S. government and the U.N. for his alleged connection to an al-Qaida-linked Somali militant group.

Hussein Khalid of the Muslim for Human Rights group says police were using teargas Tuesday and the protesters threw stones. Khalid said one person was stabbed and hospitalized.

Regional police boss Aggrey Adoli said officers were forced to contain the youth after protests Monday led to the death of one person and the vandalism of two churches and businesses.
