At least 29 people were missing after a crowded boat sank in the Kosi river in east Nepal on Sunday, police said.
The incident took place in Sunsari district, 200 km (125 miles) southeast of Kathmandu.
"Eleven of the estimated 40 people on the boat have been rescued and the search for the rest is continuing," the police control room in Kathmandu said.
Details were not available.
Boats are often crowded in mountainous Nepal, which does not have enough good roads and bridges.
