In India, at least 48 people have died since June 14, after heavy rains battered the northeastern state of Assam, according to its disaster management authority, triggering landslides and causing river banks to swell. More than 5.5 million people have been affected in the state alone, the authority added.
Assam's Chief Minister, Himanta Biswa Sarma, on Tuesday visited one of the 1,687 relief camps, housing more than 260,000 displaced people in the state.
"Our Govt will soon launch a portal for the affected people to register their livestock loss and other damages caused by floodwaters," he wrote on Twitter. "A flood relief package too will be announced shortly."

The downpour has caused catastrophic flooding in the northeastern Sylhet region, local officials said.

Extreme weather events in South Asia are becoming increasingly frequent due to the climate crisis, with temperatures in parts of India and Pakistan reaching record levels during a heatwave in April and May. Scientists said the climate crisis had made the possibility of a record-breaking heatwave hitting India and Pakistan "100 times more likely."
A 2022 report by the Intergovernmental Panel on Climate Change said they had medium confidence that heatwaves and humid stress would become more "intense and frequent," and that "annual and summer monsoon precipitation will increase."
