On Wednesday, authorities had said 133 Indians and 37 NRIs were among nearly 500 people missing. At least 50 of the Indians were pilgrims travelling for the Kailash Manasarovar Yatra.
Separate updates from the Indian states have also highlighted the scale of the crisis. NORKA Roots said 53 Keralites, including children, were estimated to be stranded in Nepal, while the Maharashtra government said 80 tourists from the state were stuck in the flood-hit country, though that figure was preliminary.
The development comes as authorities continue to assess the scale of the disaster and track people reported missing after the flash flood in Nepal's Rasuwa district.
