Kenya: Deadly grenade attack in Kenyan capital

A series of explosions at a bus station in the Kenyan capital Nairobi have killed at least four people and wounded 40 others, the Kenyan Red Cross has said. The Red Cross reported on its official Twitter account that eight out of the 40 injured people admitted to hospital on Saturday are in a critical condition. Kenyan police immediately blamed al-Shabab, the Somali Islamist armed group, that Kenyan troops are currently fighting in neighbouring Somalia.
