As many as 21 National Disaster Response Force (NDRF) teams have been deployed across 12 flood-affected districts in Bihar, rescuing more than 3,500 people. Following the breach in the embankments in east Champaran and Gopalganj districts, NDRF teams reached there to carry out relief and rescue operations.

The river embankment, near Bhawanipur village in east Champaran, was breached on July 23-24 night due to the surging flood waters of the Gandak river. As soon as the embankment gave way, Bhawanipur village was inundated, affecting hundreds of people.
