Rescuers searching the flood-hit Rasuwagadhi Hydropower Project in Nepal's Rasuwa district found no signs of people inside its tunnel on Monday, even as 93 workers at the project remain untraced.

"The rescue team led by the Nepali Army has returned after searching the tunnel of the 111-MW flood-affected project in Rasuwa and finding no people inside," the Prime Minister's Secretariat said on Monday.
