Explosion at oil refinery

More than 50 people were killed and many injured when an explosion rocked an illegal oil refinery in southeastern Nigeria, state officials and police said Saturday, local time. The death toll may be more than 100, according to a report in the Lagos-based Punch newspaper. The fire was reported to have spread to nearby properties. The fire broke out Friday night and quickly spread to two fuel storage areas at the illegal crude oil refinery, causing the complex to be ‘‘engulfed by fire which spread rapidly’’ within the area, said Declan Emelumba, the Imo State commissioner for information. The cause of the explosion and the extent of the deaths, injuries and damage were being investigated.
