With the Kosi River continuing to unleash its fury in Bihar districts bordering Nepal, the army has been called out to help over 20 lakh marooned people.
According to the Central Water Commission, the rivers Kosi, Ganga, Ghaghra, Punpun and Burhi Gandak are flowing above the danger mark at several places along their respective courses.
The flood has affected 15 districts - Muzaffarpur, Patna, Katihar, Nalanda, West Champaran, Khagaria Sheikhpura, Purnia, Saran, Begusarai, Bhagalpur, Supaul, Saharsa, Madhepura and Araria.
Acres of human habitation and farmlands have been submerged by the waters of the Kosi river.
About a lakh marooned people have been evacuated so far, the bulk of them by government boats and many on their own. Four helicopters and 200 country boats are working overtime to ferry the men and material to safe destinations.
