NAIROBI, Kenya (AP) — The Kenya Red Cross says at least 10 people were wounded in a grenade attack on a church service at a police camp in northern Kenya.
According to the Red Cross the attack took place at the Utawala Interdenominational church in the town of Garissa.
Kenya has been hit by a string of grenade attacks that are blamed on sympathizers of al-Shabab, Somalia's Islamist extremist rebels who are linked to al-Qaida.
Al-Shabab has vowed to carry out attacks on Kenya because it sent army troops into Somalia last year to fight the rebels, who are considered a threat to Kenya's security because they have been blamed for kidnapping foreign tourists and aid workers in Kenya.
