At least 22 people died as the fiercest cyclone to hit parts of Bangladesh and eastern India this century sent trees flying and flattened houses, with millions crammed into shelters despite the risk of coronavirus.
Millions were left without power after Cyclone Amphan, packing winds of around 150 kilometres per hour, carried away electricity pylons, walls and roofs, officials said on Thursday as they began to assess the damage.
Residents in the Indian city of Kolkata, the capital of the hard-hit West Bengal state, awoke to flooded streets with some cars window-deep in water and television footage showed the airport inundated.
"The impact of Amphan is worse than coronavirus," Mamata Banerjee, chief minister of West Bengal, told local media, saying that at least 12 people had died in the state.
"Thousands of mud huts have been levelled, trees uprooted, roads washed away and crops destroyed," she said.
