At least 20 people were killed and more than 200 injured when an earthquake hit southern Pakistan, disaster management authority director general Naseer Nasir said on Thursday.
The 5.7 magnitude earthquake struck Thursday morning as people slept. Rescuers said the dead were mostly women and children.
The quake was relatively shallow 20 km away with an epicenter 102 km east of Quetta, the US Geological Survey (USGS) said.
More than 100 mud houses collapsed and scores were damaged, including government buildings. Hundreds of people were left homeless, Harnai city deputy commissioner Sohail Anwar told Reuters.
Social media showed houses shaking and lightings swaying as the quake struck, and later stunned residents gathered on the street in the dark.
The injured were rushed to hospital, while some were treated on stretchers in the street by phone torchlight.
A 7.7 magnitude earthquake struck Quetta in 1935, killing between 30,000 and 60,000 people, making it one of the deadliest earthquakes in South Asian history.
