A suspected grenade attack on a minibus in Kenya's capital on Saturday killed at least four people near a Somali-dominated area of the city, police said, an incident that mirrors explosions last year that were blamed on Somali militants. "So far I can confirm that four people have died in the explosion," Benson Kibui, Nairobi county police commander, told Reuters, without giving details. Another police officer described it as a grenade attack. http://english.ahram.org.eg/News/89109.aspx
