KARACHI: A blast reportedly due to a boiler exploding in a factory along the North Karachi industrial area has claimed at least eight lives so far, mostly labourers while injuring dozens on Tuesday as the building roof collapsed. Senior superintendent of police in East district alongside his personnel has taken over the blast site as paramedic teams carry out their rescue exercise on the scene.

According to the reports so far, the blast and its aftermath have broken apart from a high tension K Electric cable which caused a power outage in the adjacent block.
