A bomb exploded in a Catholic church on the outskirts of the Nigerian capital Abuja during Christmas prayers on Sunday and emergency services said they did not have enough ambulances available to evacuate all the dead and the wounded.
The precise number of dead and wounded in the blast was not immediately available.
It was not known who exploded the bomb but Nigerian security forces are battling the militant Islamist Boko Haram group, which wants to impose Islamic sharia law across the country split roughly equally between Christians and Muslims.
