At least 350 people have been killed and many more are missing, the UN says, after a landslide hit the north-east Afghan province of Badakhshan.
Hundreds of homes were buried under mud and rocks when a section of a mountain collapsed following torrential rain.
Rescuers have reached the area and are searching for survivors.
Much of north and east Afghanistan has been hit by heavy rain in recent days, and some 150 people have died in flooding.
"The number of deceased has increased to 350 and significant displacement is expected," the UN mission in Afghanistan said in a statement.
"The UN Office for the Co-ordination of Humanitarian Affairs (OCHA) is helping... local authorities to rescue those still trapped."
