West Bengal Chief Minister Mamata Banerjee said at least 10 people had died in the state, and two districts been completely battered by one of the strongest storms to hit the region in several years.

“Area after area has been devastated. Communications are disrupted,” Banerjee said, adding that although 500,000 people had been evacuated, state authorities had not entirely anticipated the ferocity of the storm.

Another 650,000 people have been moved to safety in the eastern Indian states of Odisha and West Bengal, authorities said, an operation carried out amid surging coronavirus infections.

It was too early to estimate a toll on life or damage to property.

Cyclone Amphan began moving inland with winds gusting up to 185 kph, Mrutyunjay Mohapatra, director general of the India Meteorological Department, told reporters.
