Kabul, Afghanistan (BBN)- At least 70 people were killed in Afghanistan and Pakistan as a powerful earthquake struck northern Afghanistan, with tremors felt in Pakistan and northern India.
At least 51 people are said to have been killed in Pakistan, with about 19 deaths reported in Afghanistan, reports BBC.
The magnitude 7.5 quake was centred in the mountainous Hindu Kush region, 75km (46 miles) south of Faizabad, the US Geological Survey reported.
Buildings were evacuated in the capitals of all three countries and communications disrupted in many areas.
In the Afghan province of Takhar, a stampede at a girls' school triggered by the quake is reported to have left 12 students dead. Another 25 students were injured.
Five people died in the eastern Afghan city of Jalalabad, hospital sources said.
Most of the casualties in Pakistan are reported to have happened in the northern tribal areas.
Officials said the quake happened at a depth of 212km. The magnitude was initially put at 7.7 but later downgraded.
People in the Indian capital Delhi ran into the streets after the tremor struck, and schools and offices were evacuated. The Delhi metro was also briefly halted.
Indian Prime Minister Narendra Modi tweeted that he had ordered an urgent assessment of any damage.
"We stand ready for assistance where required, including Afghanistan and Pakistan," he said.
Catherine Bhatti, from Durham in the UK, was visiting relatives in Sarghoda, Pakistan, when the quake struck.
"It came out of the blue, everything started to move slightly then it became stronger. We made our way downstairs and gathered outside on the lawn," she told the BBC.
"My in-laws, who have lived here all their lives, say they have never experienced anything like this before."
David Rothery, a professor of planetary geosciences at the UK's Open University, said the quake had the potential to be very damaging.
"Fortunately it occurred at a depth of more than 200km and so the shaking of the ground surface was less than it would have been for a shallower earthquake of the same magnitude," he said.
The region has a history of powerful earthquakes caused by the northward collision of India with central Asia.
In 2005, a magnitude 7.6 quake in Pakistan-administered Kashmir left more than 75,000 people dead.
In April this year, Nepal suffered its worst earthquake on record with 9,000 people killed and about 900,000 homes damaged or destroyed.
