The disaster adds to the challenges facing the country’s interim government, which came to power only weeks ago after nationwide protests forced out the previous administration.

Days of heavy rainfall have crippled transportation networks, cutting off Kathmandu, the federal capital, from much of the country. Major highways remain blocked, and several domestic flights have been suspended. The disruption has stranded hundreds of travelers returning from Dashain, Nepal’s largest Hindu festival.

Authorities closed all government offices on Sunday and Monday as the scale of the emergency became clear.

According to the Armed Police Force, most casualties occurred in Koshi Province in southeastern Nepal, where landslides swept away several homes. Two others are dead in flooding, while at least 11 people, including four trekkers on the popular Langtang route, remain missing.

The army has deployed helicopters and rescue teams in more than 20 affected areas to search for survivors and deliver relief supplies. Central provinces such as Bagmati and Madhesh have also been hit hard, with widespread damage to homes and infrastructure.

In the Kathmandu Valley, emergency services evacuated residents living along riverbanks as rising waters entered densely populated neighborhoods.

Officials warned that the death toll could rise as rescue efforts continue in remote mountain areas cut off by debris and collapsed roads.
