A new earthquake has hit western Afghanistan - several days after two large tremors in the region killed more than 1,000 people.
The US Geological Survey (USGS) says the magnitude 6.3 quake struck near the city of Herat. It was at a depth of 6.3km (four miles).
So far there have been no reports of any casualties.
More than 90% of those who died in the earlier quakes were women and children, the UN's children agency Unicef said.
In its report, the USGS said the epicentre of the latest tremor was 30km north-west of Herat, Afghanistan's third-largest city close to the Iranian border.
Last Saturday's earthquake hit Zindajan, a rural district some 40km from Herat.
The tremor saw entire houses, which were too fragile to withstand the quake, reduced to rubble.
Villagers used shovels and bare hands to search for missing people.
Afghanistan has been reeling from an economic crisis since the Taliban takeover in 2021, when aid given directly to the government was stopped.
The country is frequently hit by earthquakes, especially in the Hindu Kush mountain range, as it lies near the junction of the Eurasian and Indian tectonic plates.
In June last year, the province of Paktika was hit by a 5.9 magnitude quake which killed more than 1,000 people and left tens of thousands homeless.
