Officials say 202 people have died in the Bihar floods. Araria is the worst-affected district.
While Mr Kumar thanked PM Modi for sending help to the flood-hit state in no time, BJP President Amit Shah thanked the Janata Dal (United) for deciding to join the National Democratic Alliance. Mr Kumar's party the JD(U) announced yesterday it will join the NDA, its old ally.
JD(U) द्वारा प्रस्ताव पारित कर NDA में शामिल होने के निर्णय का मैं स्वागत करता हूँ।- Amit Shah (@AmitShah) August 19, 2017
Mr Kumar said the government will help people in the flood-hit districts to rebuild their lives. "There will be no shortage of funds," the chief minister said. "...The disaster victim has the first right to the government's funds," he added.
Mr Kumar is also scheduled to visit a relief camp to check its condition. In the past five days, over four lakh people have taken shelter at 1,336 relief camps.
Heavy rain in the entire Himalayan region has also triggered floods in Assam. In Bihar, the state disaster management department has asked people living in low lying areas to move to higher places as heavy rains continued.
Water level in major rivers in the state including the Koshi, Mahananda, Gandak, Bagmati and Ganga have been in spate, officials said.
