A fresh magnitude-5.2 aftershock has struck eastern Afghanistan - two days after a powerful quake in the same region killed more than 1,400 people and injured 3,000 others, according to the Taliban government.
Rescue efforts following Sunday's magnitude-six quake have been complicated by landslides that have blocked roads, making land travel difficult.
Helicopters have been deployed to aid the search for survivors in the ruins of remote villages, where many are feared trapped under the rubble. The Taliban government - which is only recognised by Russia - has appealed for international help. The UN has released emergency funds, while the UK has pledged £1m ($1.3m) in aid.
Afghanistan is prone to earthquakes, but Sunday's tremor was one of the strongest to hit in recent years. The aftershock on Tuesday came at 12:29 (07:59 GMT) with its epicentre 34km (21 miles) away from Jalalabad, the country's fifth-largest city, according to the US Geological Survey (USGS). It was shallow, at only 10km deep.
A BBC reporter in the Sawkai district - one of the worst affected areas in the north-eastern Kunar province - said they felt a strong jolt. There are no reports of damage or new casualties. Helicopters are being used to airlift survivors out of remote villages in Kunar province - where most of the deaths and injuries occurred.
The terrain was so rough in one part of the Mazar valley that one helicopter failed to land after three attempts, one Taliban source said. Survivor Bas Marjana told the BBC: We were all in deep, peaceful sleep when... a sudden tremor struck, and the world turned upside down. She said she was rescued from underneath the rubble of her home, but several other family members were buried.
Aid agency Save the Children has sent medical teams to Kunar to address urgent needs for food, water and shelter. With the humanitarian crisis worsening, global partners including India's government, which has delivered 1,000 tents to Kabul, are stepping in amid an unprecedented situation for Afghanistan.
