• Thousands of trees were uprooted in the gales, electricity and telephone lines brought down and houses flattened.
• Many of Kolkata's roads are flooded and its 14 million people without power.
The eastern Indian city of Kolkata has been devastated by a powerful cyclone which has killed at least 84 people across India and Bangladesh.
Storm Amphan struck land on Wednesday, lashing coastal areas with ferocious wind and rain. It is now weakening as it moves north into Bhutan.
Thousands of trees were uprooted in the gales, electricity and telephone lines brought down and houses flattened.
Many of Kolkata's roads are flooded and its 14 million people without power.
The storm is the first super cyclone to form in the Bay of Bengal since 1999. Though its winds had weakened by the time it struck, it was still classified as a very severe cyclone.
Coronavirus restrictions have been hindering emergency and relief efforts. Covid-19 and social-distancing measures made mass evacuations more difficult, with shelters unable to be used to full capacity.
Amphan began hitting the Sundarbans, a mangrove area around the India-Bangladesh border home to four million people on Wednesday afternoon, before carving north and north-eastwards towards Kolkata, a historic city that was the capital of the British Raj.
Parts of West Bengal and Orissa (Odisha) states in India, and areas in south-west Bangladesh, bore the brunt, with winds gusting up to 185km/h (115mph).
At least 72 people have died in India's West Bengal state while 12 deaths have been confirmed in Bangladesh.
West Bengal chief minister Mamata Banerjee said the devastation in Kolkata, the state capital, was "a bigger disaster than Covid-19".
"Area after area has been ruined," Ms Banerjee was quoted as saying by the Press Trust of India news agency. "I have experienced a war-like situation today."
Three districts in West Bengal - South and North 24 Parganas and East Midnapore - were very badly hit. In Bangladesh, the worst-affected district was Satkhira, where large areas have been flooded as embankments collapsed in several places.
Initial assessments of the damage are being hampered by blocked roads and flooding in all these areas.
BBC Bengali's Amitabha Bhattasali in Kolkata says much of the city and its neighbouring districts have been without electricity for a day. Mobile phone networks are not working in some of the worst-hit areas.
Dramatic images shared on social media showed electricity transformers exploding in busy neighbourhoods as the storm swept the city.
"Thank God, we are safe," said a resident, who shared footage of tiled roofs being peeled off by the force of the wind and blown away.
Local news networks showed uprooted traffic lights in flooded streets, as well as broken river jetties and vehicles crushed under fallen trees.
