Reuters reports — Kenyan police fired tear gas to disperse rioters who attacked ethnic Somalis in the Nairobi district known as "Little Mogadishu" on Monday, hurling rocks and smashing windows after a weekend bomb attack there killed nine people.

The violence coincided with the start of voter registration for a general election in March, adding to security concerns ahead of the first national polls since 2007 when a dispute over the results fuelled ethnic slaughter that killed more than 1,200 people and forced some 300,000 from their homes.

Angry mobs broke into Somali homes and shops in anger at Sunday's attack on a minibus which killed at least nine people in Nairobi's Eastleigh district which is dominated by Somali Kenyans and their ethnic kin who have fled fighting in Somalia.
