Initial reports say at least 20 people dead after magnitude 5.7 quake strikes east of Quetta.
At least 20 people have been killed and 100 injured after an earthquake hit southern Pakistan in the early hours of Thursday morning, a senior Balochistan official told Al Jazeera.
“There has been quite a lot of landsliding, and teams are currently working to clear the roads to the area,” Balochistan Home Minister Zia Langove told Al Jazeera by telephone as he confirmed the latest death toll.
Rescue officials will be able to conduct a more accurate assessment of the damage once they have access to the area, he said.
Langove said most of the casualties appeared to be the result of houses having collapsed.
The earthquake struck at about 3am (22:00 GMT), as many people were sleeping, close to Harnai, a remote, mountainous city about 100 kilometres (60 miles) east of the city of Quetta, Balochistan’s provincial capital, which is near to the Afghanistan border.
The European Mediterranean Seismological Centre (EMSC) recorded the earthquake at a magnitude of 5.7, upgraded from an earlier magnitude of 5.4.
The US Geological Survey said the quake had a magnitude of 5.7 and a depth of about 20 kilometres (12 miles).
Pakistan is susceptible to earthquakes as it straddles the boundary where the Indian and Eurasian tectonic plates meet.
