Nairobi (dpa) – At least three people died and 40 were injured in a grenade attack at a busy bus station in Nairobi, the Kenyan Red Cross said Saturday. Police were quick to point the finger at Somalia's Islamist insurgent group al-Shabab, which has been blamed for previous grenade blasts in Kenya. The Red Cross said on its Twitter feed that eight of those hospitalized were in critical condition a few hours after the blast struck the Machakos Country bus station, near the center of the Kenyan capital. As many as four grenades had been thrown from a vehicle at the bus station, police said. The attack is the first in Nairobi since October. The attacks then, on a bus station and a bar, were blamed on a Shabab sympathizer and came shortly after Kenya sent forces into Somalia. Kenya got involved in Somalia's insurgency after a series of kidnappings of tourists and aid workers from Kenyan soil near the border. Nairobi blamed al-Shabab for the abductions, which threatened Kenya's crucial tourism industry, although the insurgents denied any involvement. The militant Islamists threatened to carry out terror attacks in Kenya, although so far action has been limited to small-scale actions in Nairobi and the border regions. Shabab has been battling to oust Somalia's internationally backed government since early 2007, although it has begun to lose ground in recent months under pressure from Kenya, Ethiopia and African Union forces.
