2nd LD: Explosions hit motor park in central north Nigerian city of Jos : witnesses

Explosions have rocked a major motor park in central north Nigerian city of Jos, just hours after a suicide bomber attacked a bus station in the northeast town of Biu, witnesses told Xinhua on Thursday.

The explosions occurred at the Bauchi Road motor park in Jos, and many people are feared killed.

A witness named Dalap Tanyong said the explosions have killed a yet unknown number of people, injuring several others and destroying many vehicles.

State police spokesperson Abuh Emmanuel, who confirmed the blast, could not ascertain casualty figure.

"I have just been told of the incident, we have mobilize our men to the scene, for now I cannot tell you number of victims," the police spokesperson said.

Another witness said the bombers who were in a car, detonated the device from the car and drove out of the scene.

"Casualty rate might be massive, because it happen twice in a busy place, Bauchi road motor park at about 6:45 p.m. local time; the first one exploded at the main motor park the second one was beside the park," she added.

A military source said troops were at the scene evacuating dead bodies and those who sustained injuries to hospitals.

Nigeria has witnessed a growing number of increasingly daring violent attacks by the Boko Haram terrorist group.

The militants, whose violent struggle for an Islamic state in northern Nigeria has killed thousands and made them the biggest threat to security in Africa's top oil-producing country, are still holding more than 200 girls kidnapped last year, an act which provoked a storm of international outrage.
