Over five dozen villages in Naugachia town in Bihar's Bhagalpur were flooded after river Ganga breached a ring embankment between Ismailpur and Bind Toli, Water Resources Department (WRD) officials said. The river set a new highest flood level (HFL) in the region on Tuesday. Around 250 feet of the embankment has been washed away by Ganga's strong currents, officials added.
