At least 100 people were killed and scores injured when fuel from a pipeline ruptured by a bulldozer caught fire and exploded on Thursday in a village near Nigeria's biggest city of Lagos, the Red Cross said.

Local watch a blaze in a northern suburb of Lagos following an explosion on an oil pipeline. An oil pipeline explosion killed about 100 people on Thursday in a northern suburb of Nigeria's biggest city Lagos, the Red Cross said.

The fireball engulfed homes and schools at Ijegun village in the Lagos district of Alimosho, and many of the dead, who included schoolchildren, were killed in the ensuing stampede as people fled in panic from the flames.

"About 100 people have so far been confirmed dead from the fire. We have so far rescued more than 20 people with injuries and taken them to hospital for treatment," a Red Cross official at the scene told Reuters.

The disaster was the latest in a series of pipeline explosions or blazes caused by damage or theft which have killed more than 1,200 people since 2000 in Nigeria, the world's eighth largest oil exporter and Africa's top producer.

The pipeline rupture at Ijegun, a village about 50 km (30 miles) from the centre of the sprawling coastal city of Lagos, occurred during work to build a road. A bulldozer moving earth struck the pipeline buried beneath the surface.

"I was returning home when I suddenly saw sparks of fire from where the grader (earthmover) was working," local resident John Egbowon said.

The fuel leaking from the broken pipe caught fire and exploded, sending people fleeing in panic.
