Intense rain and flooding across northeastern India from this year's monsoon season have left dozens dead across the region.

Several hundred villages were completely cut off by high water in the Indian state of Assam, where at least 84 people were killed and 2.75 million have been displaced since May.

“The flood situation remains critical with most of the rivers flowing menacingly above the danger mark,” Assam water resources Minister Keshab Mahanta told Reuters on Sunday.
