At least 48 people have been killed, and 31 others have gone missing in floods and landslides caused by unseasonal rainfalls in Nepal over the last three days.

After the monsoon season receded two weeks ago, the unexpected rainfalls flooded rivers and streams and sparked landslides across the country.

"In addition to 48 deaths and 31 missing, 23 people have been reported injured by Wednesday afternoon," Phanindra Mani Pokharel, spokesperson for the Ministry of Home Affairs, told Xinhua. "The casualties might increase."
