At least nine people were killed and scores injured Monday when a strong 6.7 magnitude earthquake struck northeast India, sending panicked residents fleeing into the streets even hundreds of kilometres away in Bangladesh.
Six were killed in India, the government said, while three people died in Bangladesh after suffering strokes or heart attacks following the early-morning quake.
Authorities in India's Manipur state where the quake was centred said another 70 people had been injured by the quake, which damaged buildings in the capital Imphal.
Imphal resident Deepak Shijagurumayum, whose house was severely damaged, described scenes of chaos.
"Almost everyone was asleep when it struck and were thrown out of their beds," Shijagurumayum told AFP by phone.
"People were crying and praying in the streets and in open spaces."
The Press Trust of India news agency said buildings had collapsed near the epicentre at Tamenglong, 20 miles from Imphal, and the electricity supply had been cut in parts of Manipur, which borders Myanmar.
Anurag Gupta of the National Disaster Management Authority said dozens of emergency workers had fanned out across the affected area, and the situation was "under control".
Manipur's Health Commissioner P.K. Singh said authorities were identifying spaces where temporary health facilities could be set up in case of stronger aftershocks, although there were no immediate reports of major damage to hospitals.
- 'State of shock' -
The US Geological Survey said the quake hit at 4:35 am (2305 GMT Sunday) 29 kilometres (18 miles) west-northwest of Imphal.
Nearly 60 victims were being treated for their injuries in hospitals in Bangladesh, where the earthquake triggered panic on the streets of major cities.
One 23-year-old Bangladeshi died after suffering a stroke when he ran out of his house, while another two people -- a farmer and a university official -- died of heart attacks, police said.
One of the injured was a university student who jumped from a fourth-floor balcony and was in critical condition.
There were similar scenes in the northeast Indian city of Guwahati, the main commercial city of the mineral-rich state of Assam, where an AFP correspondent said residents were "in a state of shock" after being woken by the shaking.
Indian Prime Minister Narendra Modi tweeted that he had spoken to local authorities in Assam about the impact of the quake.
The tremors were felt as far away as Kolkata some 600 kilometres distant in the Indian state of West Bengal, where buildings shook.
"Many people were seen coming out of their homes in panic," said local resident Rabin Dev.
India's seven northeastern states, joined to the rest of the country by a narrow sliver of land, are located in an area of frequent seismic activity.
In 1950 dozens of villages were swallowed in a string of disasters generated by a powerful earthquake whose epicentre was in Tibet but which caused the greatest destruction to India's Assam state.
More than 1,500 people died in the quake, which had a magnitude of 7.6, and its disastrous aftermath of landslides and floods.
There were no immediate reports of casualties Monday on the Myanmar side of the border, a remote and sparsely populated area that suffered widespread damage this summer from landslides caused by torrential monsoon rains.
