More than 2,100 are confirmed to have been killed after a landslide crashed into a remote mountain village in northeast Afghanistan, a spokesman for the provincial governor said on Saturday.
"More then 2,100 people from 300 families are all dead," Naweed Forotan, a spokesman for the Badakhshan provincial governor, told Reuters.
The United Nations said the focus was now on the more than 4,000 displaced by Friday's disaster. There is a risk of further landslides in the area, officials say.
Triggered by heavy rain, the side of a mountain collapsed into the village in Argo district at around 11am as people were trying to recover their belongings and livestock after a smaller landslip hit their homes a few hours earlier.
"As the part of the mountain which collapsed is so big, we don't believe anyone would survive. The government and locals from surrounding villagers are helping with the rescue, and so far they have recovered more then a hundred bodies," said an official.
Earlier, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) put the number of fatalities at 350.
At least 100 people were being treated for injuries, according to Colonel Abdul Qadeer Sayad, a deputy police chief of Badakhshan, which borders Tajikistan. Hundreds of mudbrick homes were crushed and hundreds more damaged, he said.
Rescue efforts have been hampered by difficult conditions due to a week of heavy rain. Seasonal rains and spring snow melt have caused heavy destruction across large swathes of northern Afghanistan, killing more than 100 people.
President Hamid Karzai ordered Afghan officials to start emergency relief efforts immediately to reach the poor village.
NATO-led coalition troops in the region were discussing search and rescue contributions with Afghan forces, the United Nations said. US President Barack Obama, in remarks before a news conference at the White House with German Chancellor Angela Merkel, expressed his condolences.
"Just as the United States has stood with the people of Afghanistan through a difficult decade, we stand ready to help our Afghan partners as they respond to this disaster, for even as our war there comes to an end this year, our commitment to Afghanistan and its people will endure," he said.
About 30,000 US soldiers remain in Afghanistan, although that number is falling as Washington prepares to withdraw by the end of this year all combat troops who battled Taliban insurgents.
