More than a million people are now homeless as flooding worsens in India's north-eastern state of Assam.
Assam's government expects "more devastation" this week
Waters have risen further in the past 24 hours, sweeping
away 16 villagers and submerging 500,000 hectares of cropland.
More than 5,000 villages have been affected by the floods.
Assam chief minister Tarun Gogoi said the army had been called out in several districts to help the civil administration rescue stranded people.
"It is raining incessantly in the catchment areas of Assam's major rivers like the Brahmaputra and its

The situation was worst in Assam's northernmost district of Dhemaji, where more than 200,000 people were made homeless when several embankments gave way to the waters of the Gai and Jiadhol rivers.
