At least 14 people were killed and 12 others injured in Pakistan`s financial capital of Karachi on Saturday when a powerful blast, apparently triggered by a gas explosion in a covered sewage channel, ripped through the building of a private bank situated on it, police said.
Most of the casualties are reportedly customers and staff present inside the HBL bank which was built on top of a covered sewage channel in Karachi`s Shershah area and collapsed following the explosion, the Express Tribune newspaper reported.
