At least 20 people have been killed after an earthquake struck Pakistan’s Balochistan province early on Thursday, officials said.
Provincial Disaster Management Authority (PMDA) officials said the death toll may increase.
Initial reports indicated that it may have measured up to 5.7 on the Richter scale at the depth of 15km. A government official said people died when structures collapsed.
Local officials say at least 300 others are thought to have been injured, with several of them rushed to hospital in critical condition.
The Reuters news agency said some people were treated on stretchers with medics using phones as torches.
Rescue operations are still underway. Many of the dead were women and children, Reuters reported.
More than 100 mud houses have collapsed and a large number of buildings were damaged, leaving hundreds of people homeless, an official told the agency.
Much of the damage appears to have affected the Harnai district, officials said.
Harnai, which is located east of the provincial capital Quetta, has a large number of coal mines.
Balochistan is Pakistan’s largest but least populated and least developed province, consistently ranking at the bottom of national human development indicator rankings.
