[Updated 10:23 a.m.] The eight deaths in the attack at St. Rita Catholic church include the suicide bomber, an emergency official told CNN.

The wounded had critical injuries and were taken to four hospitals in Kaduna, said Musa Ilallah, regional coordinator for the National Emergency Management Agency said.

As NEMA responded, angry Christian youth began "beating our staff and as a result broke the side glass of our ambulance that was on the scene to provide service," said Ilallah, who spoke to CNN from the scene of the attack.

[Updated 9:10 a.m.] At least eight people were killed and 100 were injured in the attack, a spokesman for the National Emergency Management Agency said.  One man was also burned alive in a reprisal attack.

Scores of people have been killed in church bombings in the country in recent years.

The Boko Haram militant Islamist group has previously claimed responsibility for church bombings that killed dozens.
