Here are the 10 facts in this big story:
After an aerial survey of the flood-hit areas of Assam, and meeting the victims in Morigaon district, Rajnath Singh said, "The situation is grim". "No efforts are being spared (to help) and the people are satisfied with government's response,' he said.
"Declaring floods as a national calamity is not a solution to the problem. There is a need for a action plan to deal with such serious flood situation," he said.
The minister, who took an aerial survey of Nagaon, Morigaon and the Kaziranga national park, was accompanied by junior Home minister Kiren Rijiju and minister for development of the north east, Jitendra Singh.
The army tweeted, saying, "Nine army columns deployed for floor relief in Assam & Bihar. 2000+ rescued. Brahmaputra breach being plugged."
