KADUNA, Nigeria: Two suicide car bombs were detonated at a church inside the Jaji military barracks in Nigeria’s northern Kaduna state on Sunday, killing at least nine people and wounding dozens, a military source said.

“A Kia branded car drove into the church premises … and detonated,” a military source who witnessed the bombings told Reuters, asking not to be named.

“Then an ash-coloured Toyota Camry drove in and exploded while people came to help after the first bomb. Most people died from the second blast,” he said.
