The explosion took place Sunday outside St. Finbar's Church in the restive city, which has been shaken by violence between Christians and Muslims.
Emergency officials say a car laden with explosives detonated as it approached the church.
Medical crews raced to the scene to transport the injured to hospitals and investigators cordoned off the area.
There was no immediate claim of responsibility for the blast.
