More than 600 people are feared dead after a magnitude 6.0 earthquake hits eastern Afghanistan, the Taliban interior ministry reports.
More than 1,300 people have been injured, the ministry says.
The quake, at a shallow depth of 8km (6 miles), shook buildings from Kabul to Pakistan's capital Islamabad, BBC reports.
The remote area where it struck makes providing accurate estimates hard, as officials warn of high casualty figures.
Dozens of houses are "under rubble", sources from the Taliban government say, while officials report entire villages being destroyed.
A 6.0 magnitude earthquake struck Afghanistan's mountainous eastern region at 23:47 local time on Sunday (20:17 BST).
Its epicentre was 17 miles (27km) away from Jalalabad, the country's fifth-largest city in Afghanistan’s eastern Nangarhar province.
The earthquake has also affected the Kunar and Laghman provinces, and was felt 140km (87 miles) away in the country's capital Kabul.
It will take a while before the extent of the earthquake's damage is fully known.
This is mountainous terrain. These areas are extremely challenging to reach even in the best of times, which is really hampering rescue and relief operations.
We've been told that the road leading to the epicentre has been blocked because of a landslide, so the Taliban government is using helicopters to get people out.
With the region being difficult to access, any kind of rescue operations are going to be slow-moving.
