Grieving Christians prayed, sang and clapped hands at an Easter Sunday service at a Catholic church in Garissa, a Kenyan town where Islamic extremists killed 148 people in an attack on a school.

Security forces patrolled the perimeter of Our Lady of Consolation Church, which was attacked by militants several years ago. Grenades lobbed at the building sprayed shrapnel into the interior, injuring some worshippers. An attack on the same day on another Garissa church killed over a dozen people.

Sunday's ceremony was laden with emotion for the several hundred members of Garissa's Christian minority, which is fearful following the attack by al-Shabab, a Somalia-based Islamic extremist group. The gunmen who attacked Garissa University College on Thursday singled out Christians for killing.
