Major casualties were feared in Nepal and Tibet. Videos showed crumbling homes in the floodwaters and floating cars as authorities urged people on the banks of the Bhote Koshi River to move to higher ground.
The Bhote Koshi River is a headwater tributary of the Kosi River system, which enters northern Bihar in Supaul after flowing through Nepal. Authorities in Bihar feared a sudden surge in water flow into the Gandak River.
The official said that teams of the National Disaster Response Force (NDRF) were being mobilised to handle any emergency. In Bihar, officials have identified areas such as Jhandu Tola, Bin Toli, Chakdahwa and Kailashnagar as vulnerable areas.
Tamil Nadu chief minister C Joseph Vijay said in a statement that he has instructed senior officials of the Tamil Nadu government at the Tamil Nadu House in Delhi to take all the necessary measures to swiftly rescue those hailing from Tamil Nadu missing in this disaster and to provide all required assistance to those affected.
Steps are being expedited to gather information about the people from Tamil Nadu through the ministry of external affairs of India and the Indian Embassy in Nepal ensuring their safety, he said
“Emergency telephone numbers have been announced to enable Tamils stranded in Nepal or their relatives in Tamil Nadu to reach out if they seek help” he added.
