Rescuers in Nepal are searching for survivors of a 7.8-magnitude earthquake that killed at least 3,200 people, including 17 on Mount Everest, digging through rubble in the devastated capital, Kathmandu.
Residents of Kathmandu were jolted by a fresh 6.7-magnitude aftershock on Sunday that compounded the worst disaster to hit the Himalayan nation in more than 80 years.
Overnight tremors had forced residents to spend the night trying to sleep out on the streets and open ground in makeshift tents.
"We don't feel safe at all. There have been so many aftershocks. It doesn't stop," said Rajendra Dhungana, 34, who spent the day with his niece's family for her cremation at the Pashuputi Nath Temple in Katmandu. "I've watched hundreds of bodies burn. I never thought I'd see so many."
Acrid, white smoke rose above Nepal's most revered Hindu temple, where dozens of bodies were being cremated at any given time.
As planeloads of supplies, doctors and relief workers arrived from neighboring countries, journalists reported on social media that aftershocks forced some aircraft to circle the Kathmandu airport while waiting to land.
Aftershocks were also reported in New Delhi, the capital of neighboring India, where the earthquake killed at least 50 people in the states of Bihar, Uttar Pradesh and West Bengal.
Most areas are without power and water, but with Kathmandu airport reopening, rescue flights began arriving. Workers are sending out tents and relief goods in lorries and helicopters.
Authorities are now reporting at least 2,500 people dead, including 1,152 in the capital, and only 799 bodies handed over to their families. The number of casualties is expected to climb as reports come in from far-flung areas, said Laxmi Dhakal, a home ministry official.
Among the dead are 17 who were struck by an avalanche on Mount Everest that buried part of the base camp packed with foreign climbers preparing to make their summit attempts.
At least 5,000 people were injured across Nepal.
Snowfall on Saturday thwarted efforts to remove survivors from the Everest base camp, where about 100 mountaineers are believed to be stuck. Rescue planes and helicopters began removing the injured to Kathmandu on Sunday.
The quake destroyed expanses of the oldest neighborhoods of Kathmandu, and was strong enough to be felt all across parts of India, Bangladesh, Tibet and Pakistan.
Kathmandu's historic nine-story Dharahara tower, a major tourist attraction and a UNESCO-recognized historical monument, was among the buildings toppled by Saturday's earthquake.
The disaster is likely to put a huge strain on the resources of Nepal, best known for Everest, the highest mountain in the world. The country’s economy relies heavily on tourism.
The world reacted quickly to the disaster, offering money, relief materials, equipment, expertise and rescue teams.
Among the first to move in was Nepal's neighbor India, with which it has close political, cultural and religious ties.
Indian air force planes landed on Sunday with 43 tons of relief material, including tents and food, and nearly 200 rescuers, said Vikas Swarup, India's External Affairs Ministry spokesperson.
