At least 15 people were killed and several others injured on Friday after a massive explosion in Pakistan's industrial hub of Faisalabad in Punjab, according to local media.
The explosion caused a building to collapse and damaged nearby structures, Dawn News reported.
Many others were injured and hospitalized, with rescue operations underway, it added.
The report said the explosion was caused by a gas leak.
"A fire erupted in one of the factories due to gas leakage and engulfed the other factories as well," it said.
