NAIROBI - Four people killed when a car bomb exploded outside a police station in a poor neighborhood of the Kenyan capital Nairobi on Wednesday, the Interior Ministry said.
Police officers had earlier stopped the saloon car at traffic lights and were taking the occupants for questioning when the bomb exploded, the ministry said.
Kenya's security forces are struggling to contain a surge in bomb and gun attacks that the authorities blame on the Somali Islamist militants who killed at least 67 people when they laid siege to Nairobi's Westgate shopping mall in September.
Kenyans are increasingly alarmed at the relative ease at which the militants and radicalized youths are able to carry out deadly strikes in the heart of Kenya, east Africa's biggest economy.
It was not immediately clear who was behind the attack.
