KARACHI, Dec 19: At least 15 people were killed and 16 others injured in an explosion on Saturday at a bank branch in Karachi's industrial area, police said.
A senior police officer said the blast at a branch of Habib Bank Limited, Pakistan's largest lender, could have been caused by a gas leak, Sarfaraz Nawaz also told reporters that the building appeared to have been constructed over a sewage drain.
"Our explosives teams are at work trying to ascertain the nature of the blast, but apparently the structure was constructed on a drain and gas could be a probable cause," he said.

A petrol station located next to the bank within the Sindh Industrial Trading Estate and cars parked nearby were badly damaged. Television footage showed the bank's floor ripped apart, exposing twisted iron bars.

Another senior police officer, Sharjeel Kharal, told reporters it was not immediately clear how many were dead or injured in the explosion as the bank had a skeleton staff on Saturday.
