Officials said at least 16 people were killed and dozens wounded in a car bomb explosion in the northern Nigerian city of Kaduna.
The blast on April 8 caused extensive damage to nearby restaurants, a hotel and two churches.
The region has been the scene of a religious conflict in recent years that has claimed many lives.
Officials said there had been warnings of attacks in the area over Easter.
No group has claimed responsibility for the Easter Sunday blast.
