Local officials in the east of the Democratic Republic of Congo say a landslide killed at least 19 people on Sunday morning.
An official in the village of Bulwa in North Kivu province said the death toll was likely to rise.
He said some members of a group of women and children who had been washing laundry in a mountain stream were buried after the ground collapsed beneath them.
The search for more victims will resume on Monday.
The region has been battered for months by heavy rains which have triggered flooding and mudslides.
