At least 10 people have been killed in a suicide bomb attack on a Catholic church in the central Nigerian city of Jos.
Eyewitnesses say the suicide bombers refused to open the boot of their car when challenged at the church gates before detonating the explosives as worshippers approached them.
The Reverend Peter Umoren was conducting a service when the attack took place.
President Goodluck Jonathan has appealed to the Nigerian people not to take the law into their own hands.
No group has yet claimed responsibility for the attack.
