Millions have been stranded or displaced as devastating floods continue to ravage large parts of India, Nepal and Bangladesh.

In India, the eastern state of Bihar and the north-eastern state of Assam have been the worst hit.

Local officials told BBC Hindi that nearly 100 people have been killed in both states.

The region was hit by monsoon rains which triggered floods and landslides, submerging homes and transport links.

Flood waters covered buildings, roads and railway lines, cutting off whole districts – such as Muzaffarpur in Bihar.

Some 4.7 million have been displaced in Bihar, one of India’s poorest states. More than 100,000 people are now living in relief camps, officials say.
