A 7.3-magnitude quake has rocked Nepal, followed by two major aftershocks. At least 37 people have been killed in the country and over 1,000 injured. It comes weeks after a disastrous quake left over 8,000 people dead, affecting millions.
Sixteen others were killed in India after rooftops or walls collapsed onto them, according to the countrys Home Ministry. Chinese media reported one death in Tibet.
The quake hit near the town of Namche Bazaar, close to Mt. Everest. It was originally given a magnitude of 7.4 by the US Geological Survey (USGS), but was later downgraded to 7.3.
This is a really big one, Prakash Shilpakar, the owner of a handicrafts shop in Kathmandu, told Reuters. Shilpakar was trying to call his parents in the town of Bhaktapur, which was destroyed in the devastating April earthquake.
Rescue helicopters have been sent to mountain areas, where landslides and collapsed buildings may have buried people, the Nepalese government said. The Sindhupalchowk and Dolkha districts were the worst hit, according to Home Ministry official Laxmi Dhakal.
It comes just a few weeks after a devastating 7.8-magnitude quake left over 8,000 people dead and almost 18,000 injured.
Around eight million people in Nepal, which has a total population of 28 million, have been affected by the disaster, the UN estimated.
Shockwaves were also felt as far away as northern India and Bangladesh.
Subway services have been halted in Indias New Delhi and Calcutta following the latest quake.
Tuesdays quake was deeper than the one in April, measuring at a depth of 18.5 kilometers (11.5 miles) versus the earlier one at 15 kilometers (9.3 miles). Shallow earthquakes tend to cause more damage.
