Floods and landslides caused by torrential monsoon rains have killed at least 50 people across Nepal while dozens more are missing, officials said Sunday.
Northeast India has also been hit by floods with 11 deaths recorded as rivers burst their banks.
Heavy rains since Thursday have hit several districts in Nepal, especially in the country's eastern region and the southern plains, affecting thousands.
Nepal police spokesman Bishwaraj Pokharel said 33 people are missing while over 1,100 people have been rescued.
"We have mobilised all resources in the country for search, rescue and relief and have been able to reach all affected areas," Pokharel told AFP.
Authorities said river levels are expected to return to normal from Monday.
