The 2nd Jos Bombo was a Car Bomb

An explosion that killed at least three people in the central Nigerian city of Jos was hidden in a car, police said on Sunday, as an investigation opened into the second deadly blast within a week.

"It was a vehicle-borne IED (improvised explosive device)," said Chris Olakpe, the commissioner of police for Plateau state, of which Jos is the capital.

"The death toll so far is three. That includes the bomber," he told AFP but did not say whether the explosion, which happened at about 9:30 pm (2030 GMT) on Saturday, was an attempted suicide attack.

At least three people were injured, he added.
