Rescuers dug with their bare hands and bodies piled up in Nepal on Sunday after an earthquake devastated the heavily crowded Kathmandu valley, killing at least 1,900, and triggered a deadly avalanche on Mount Everest.
Army officer Santosh Nepal and a group of rescuers worked all night to open a passage into a collapsed building in the capital Kathmandu. They had to use pick axes because bulldozers could not get through the ancient city's narrow streets.
"We believe there are still people trapped inside," he told Reuters, pointing at concrete debris and twisted reinforcement rods where a three-storey residential building once stood.
In Everest's worst disaster, the bodies of 17 climbers were recovered from the mountain on Sunday after being caught in avalanches, but hundreds, many injured, remain stranded on the mountain.
With the government overwhelmed by the scale of the disaster, India flew in medical supplies and relief crews, while China sent in a 60-strong emergency team.
Among the capital's landmarks destroyed in the earthquake was the 60-metre (200-foot) Dharahara Tower, built in 1832 for the queen of Nepal, with a viewing balcony that had been open to visitors for the last 10 years.
A jagged stump was all that was left of the lighthouse-like structure. As bodies were pulled from the ruins on Saturday, a policeman said up to 200 people had been trapped inside.
Bodies were still arriving on Sunday morning at one hospital in Kathmandu, where police officer Sudan Shreshtha said his team had brought 166 corpses overnight.
"I am tired and exhausted, but I have to work and have the strength," Shreshtha told Reuters as an ambulance brought three more victims to the Tribhuvan University Teaching Hospital.
Bodies were heaped in a dark room; some covered with cloth, some not. A boy aged about seven lay, his face half missing and his stomach bloated like a football. The stench of death was overpowering.
Outside, a 30-year-old woman who had been widowed wailed: "Oh Lord, oh God, why did you take him alone? Take me along with him also."
Some buildings in Kathmandu toppled like houses of cards, others leaned at precarious angles, and partial collapses exposed living rooms to with furniture in place and belongings stacked on shelves.
Rescuers, some wearing face masks to keep out the dust from collapsed buildings, scrambled over mounds of splintered timber and broken bricks in the hope of finding survivors. Some used their bare hands to fill small white buckets with dirt and rock.
Thousands of people spent the night outside in freezing temperatures and patchy rain, too afraid to return to their damaged homes.
On Sunday, survivors wandered the streets clutching flimsy bed rolls and blankets, while others sat in the street cradling their children, surrounded by a few plastic bags of belongings.
The 7.9 magnitude quake struck at midday on Saturday at a busy time of year for the tourism-reliant country's trekking and climbing season, with an estimated 300,000 foreign tourists in the country.
Nepal's police put the death toll at 1,910, with 4,625 injured. At least 700 were killed in the capital, a city of about 1 million people where many homes are old, flimsy and packed close together.
The road west from Kathmandu to the valley of the same name was still open, with trucks and buses passing through police checkpoints. Many people spent the night in taxis or buses as tremors continued.
WORST EVEREST DISASTER
Foreign climbers and their Nepalese guides around Mount Everest were caught by the tremors and a huge avalanche that claimed the highest toll of any disaster on the world's highest mountain.
Seventeen bodies were recovered on Mount Everest base camp and 61 were injured when part of the base camp was engulfed by the snowslide, Ang Tshering Sherpa, president of the Nepal Mountaineering Association, told Reuters.
A first helicopter took off from Kathmandu on Sunday morning to airlift the injured after flights were delayed by cloudy weather, Sherpa said.
Two light helicopters shuttled the injured from base camp to a lower altitude, from where they could be evacuated back to the capital, emergency officials at Kathmandu airport said.
Hospitals across the impoverished nation of 28 million people struggled to cope with its worst quake in 81 years. They expected a fresh influx of patients on Sunday but medical supplies were running low.
PEOPLE STILL TRAPPED
The earthquake, centred 50 miles (80 km) east of the second city, Pokhara, was all the more destructive for being shallow.
Rescue operations had still not begun in towns in some remote areas. Across the capital, rescuers scrabbled through destroyed buildings, among them ancient, wooden Hindu temples.
"I can see three bodies of monks trapped in the debris of a collapsed building near a monastery," Indian tourist Devyani Pant told Reuters. "We are trying to pull the bodies out and look for anyone who is trapped."
Neighbouring India, where 44 people were reported killed in the quake and its aftershocks, sent military aircraft to Nepal with medical equipment and relief teams. It also said it had dispatched 285 members of its National Disaster Response Force.
In Tibet, the death toll climbed to 17, according to a tweet from China's state news agency, Xinhua.
International aid groups readied staff to go to Nepal to help provide clean water, sanitation and emergency food, while the United States, Britain and Pakistan were among countries providing search-and-rescue experts.
More than 1,000 climbers were on Everest at the start of their season when disaster struck.
The first injured were helicoptered out in the morning, Romanian climber Alex Gavan tweeted from base camp.
"All badly injured heli evacuated," Gavan said. "Caring for those needing. want sleep."
Another 100 climbers higher up Everest at camps 1 and 2, were safe but their way back down the mountain was blocked by damage to the treacherous Khumbu icefalls, scene of an avalanche that killed 16 climbers last year.
In the Annapurna mountain range, where scores were killed in the nation's worst trekking accident last year, many hikers were stranded after the quake, according to messages on social media, but no deaths there had been reported.
Nepal, sandwiched between India and China, has had its share of natural disasters. Its worst earthquake in 1934 killed more than 8,500 people.
