A powerful gas explosion in a sewage system in Pakistan has killed at least 12 people and injured 11 others, police and medics said.

Police spokesman Sohail Jokhio said the blast was apparently caused when something ignited gas that had accumulated in the sewer beneath a bank building in the Shershah neighbourhood of the port city of Karachi.
