Millions of people have been affected by flooding in northern India after a river completely changed its course.
About 2.5 million people have been forced out of their homes after a dam burst, sending the Kosi river on a completely different route.
More than 70 people have now died and hundreds of thousands are stranded without food or drinking water.
More rain is expected in the region and authorities are trying to get people to safety before it falls.
Tens of thousands of people have already crowded into temporary refugee camps, but there are fears they do not have enough to eat.
Indian Prime Minister Manmohan Singh, who visited the affected areas in Bihar on Thursday, said the flooding was a "national calamity".
