Kenya's Red Cross says gunmen have attacked a civilian vehicle with rocket-propelled grenades and machine guns near the Kenya-Somali border, killing four people.
Kenyan Red Cross spokeswoman Nelly Muluka-Oluoch says that Red Cross personnel who went to the site of the attack in far northeast Kenya say that four people died. The Red Cross personnel say machine guns and rocket propelled grenades were used against the vehicle, which was carrying school examination papers.
The attack comes a little less than two weeks after Kenya sent hundreds of troops into Somalia to attack al-Shabab militants. Al-Shabab has threatened to carry out attacks in Kenya in retaliation.
