Tens of thousands displaced in northeast India floods

STORY: Roads and railway lines were submerged, with people wading through waist-high brown churning waters, carrying their belongings and livestock.

Many of India's rivers rose to dangerous levels, breaking their natural embankments and inundating floodplain areas.

A humanitarian crisis could emerge if the floods do not recede and proper rescue operations are not conducted.

In Assam, armed forces were called in for rescue efforts after landslides killed at least nine people and displaced 1.9 million from their homes in the last 10 days.

Torrential rains lashed 25 of the state's 33 districts for a sixth day.

India has experienced increasing extreme weather in recent years, causing large-scale damage. Environmentalists warn climate change could lead to more disasters, especially in low-lying and densely populated areas.
