Landslides and floods triggered by torrential rains in Nepal have killed at least 15 people in the last three days, officials said Sunday.

"Five bodies were recovered Sunday morning after they were swept away by a flooding river in Rautahat late Saturday," local official Durga Prasad Bhandari told AFP from Rautahat district, 80 kilometres (50 miles) south of Kathmandu.

Bhandari said the victims were attempting to push a van stuck in the Dhansar River when the flood waters overwhelmed them.

Five people died in landslides on Saturday in Kaski district, 140 kilometres west of the capital, said home ministry official Ishwor Regmi. Five others died in nearby districts on Friday.

The deaths took to 183 the toll from monsoon-triggered landslides and floods in the Himalayan nation since June, according to the home ministry.
