At least 50 people have been killed and more than two million affected by heavy monsoon flooding in the north-eastern Indian state of Assam, officials say.

A video of a minister wading into muddy waters to rescue people has highlighted the plight of those hit by the floods. 

Heavy rain has submerged thousands of villages. Hundreds of relief camps have been set up to shelter those displaced.

A heavy monsoon in the region is common, but this year comes as India battles rising Covid-19 infections.
