An earthquake of magnitude 6.1 killed at least 280 people in Afghanistan early on Wednesday, officials said, adding that hundreds of people were injured and the toll was likely to rise as information trickled in from remote mountain villages, Reuters reports.
The quake struck about 44 km (27 miles) from the city of Khost, near the Pakistani border, the U.S. Geological Survey (USGC) said.
"Strong and long jolts," a resident of the Afghan capital, Kabul, posted on the website of the European Mediterranean Seismological Centre (EMSC).
"It was strong," said a resident of the northwestern Pakistani city of Peshawar.
Photographs on Afghan media showed houses reduced to rubble and bodies covered in blankets on the ground.
The EMSC put the magnitude at 6.1 though the USGC said it was 5.9.
Most of the confirmed deaths were in the eastern Afghan province of Paktika, where 255 people had been killed and more than 200 injured, said interior ministry official Salahuddin Ayubi.
In Khost province, 25 people had been killed and 90 taken to hospital, he said.
"The death toll is likely to rise as some of the villages are in remote areas in the mountains and it will take some time to collect details," he said.
Authorities had launched a rescue operation and helicopters were being used to reach the injured and take in medical supplies and food, he added.
Shaking was felt by about 119 million people in Pakistan, Afghanistan and India, the EMSC said on Twitter.
There were no immediate reports of damage or casualties in Pakistan.
