One child has died and three others have been seriously wounded after an explosive device went off in a Sunday school class in Kenya’s capital, acting police chief Moses Ombati said.
Mr Ombati said he suspects sympathisers with the Somali militant group al Shabab were behind the attack at an Anglican church in Nairobi.
Kenya has seen a series of attacks on churches ever since Kenyan forces moved into Somalia to fight al Shabab last year.
Kenyan forces kicked the rebels out of their last stronghold, Kismayo, on Friday.
Grenades are often used in the attacks. Mr Ombati described the cause of Sunday's attack as an explosive device.
One church member, Julius Macharia Maina, brought four children to the hospital.
One child's head was cut open, while others had bruises.
