NAIROBI, Kenya - An official says ten people were wounded when a grenade was thrown into a church in Kenya's capital during Sunday service.
Deputy police spokesman Charles Owino said Sunday that the grenade exploded at Gods House of Miracle Church in Nairobi.
The incident is the latest in a string of grenade attacks since Kenya sent troops into Somalia in October last year.
It follows a U.S. embassy warning that a terror attack on prominent government buildings and hotels in Nairobi could be imminent.
The embassy said Monday that the timing of the attack is not known but they believe it to be at a final planning stage.
Al-Qaida-linked al-Shabab militants from neighbouring Somalia have vowed to carry out a major attack on Kenya for sending troops into Somalia.
