Government officials say floods and landslides triggered by monsoon rains in Nepal have killed 54 people over the last two days.

Home ministry spokesman Yadav Prasad Koirala said Wednesday that at least 20 people were missing.

Hundreds of people have been displaced after swollen rivers breached their banks and flooded homes.

Soldiers and volunteers used rubber boats to rescue people marooned by the flooding, while helicopters were being used to drop food supplies.

Koirala said the situation was serious in eight districts, and that road links to some areas were cut by the flooding.

Tens of thousands of people are still living in tents following a set of devastating earthquakes that hit the Himalayan country last year.
