 KATHMANDU A Nepali-French search and rescue team pulled a 28-year-old man, Rishi Khanal, from a collapsed apartment block in the Nepalese capital of Kathmandu on Tuesday after he had spent around 80 hours in a room with three dead bodies. 
 
 Khanal appeared to have had no access to food or water during his ordeal, which began at midday on Saturday when a 7.9 magnitude earthquake hit Nepal, destroying buildings and killing at least 4,600 people. 
 
 "It seems he survived by sheer willpower," said Akhilesh Shrestha, a doctor who treated him. 
 
 Khanal had been on the second floor of a seven-storey building when the quake struck. The top floors were intact and the teams drilled down to him after he shouted for help and responded to questions in Nepali. 
 
 The rescue took five hours. Doctors think he may have a broken leg.

 Aid has begun to reach remote regions near the epicentre of Saturday's devastating earthquake in Nepal. 
 
 As relief efforts continue in the Kathmandu Valley, the UN says the response is broadening to include hard hit areas such as Dhading and Gorkha. 
 
 The 7.8-magnitude quake killed more than 5,000 people. Many survivors are in desperate need of food and water. 
 
 Thousands of people are queuing to board buses and leave the capital, amid fears of further aftershocks. 
 
 "We are scared of the epidemics that may spread because of all those dead bodies," a man waiting at Kathmandu's main bus station told the BBC. "Just to be safe, I'm leaving town for a while." 
 
 Early on Wednesday police at the station scuffled with people trying to get on to crowded buses.

 There's a rush to get out of Kathmandu. Thousands of people are trying to flee - some trying to head out to the remote districts to see how their families are, others including tourists trying to head towards India by road. 
 
 But there simply aren't enough buses to take them out and the highways are choked with vehicles, people and relief convoys. Tempers are flaring. The police came to the bus station to restrain those trying to board crowded buses, which made it worse. 
 
 Outside Kathmandu airport, there are lines of tourists trying their best to get a ticket to fly home. The airlines have laid on extra flights but it's not enough and also, the airport is finding it hard to cope with the additional rush as well as the influx of cargo aircraft bringing in relief material.

 Rescue operations resumed on Wednesday following bad weather. 
 
 Bella Messenger, an NGO worker in an isolated area of Gorkha district, told the BBC that Chinese lorries had brought aid to the area, but many people remained cut off. 
 
 "You can't get to some villages without a helicopter," she said. 
 
 There was some good news when a man trapped in the rubble of a Kathmandu hotel for 82 hours was pulled to safety by Nepalese and French teams. 
 
 Rishi Khanal, 27, said he had been surrounded by dead bodies and drank his own urine to survive. 
 
 "I had some hope but by yesterday I'd given up. I was sure no-one was coming for me. I was certain I was going to die," he told AP news agency from his hospital bed.

 More than eight million people have been affected by the quake, the UN says. About 10,000 people have been injured. 
 
 Hundreds of thousands of people continue to live in temporary camps, in squalid conditions with very little food and water, says the BBC's Sanjoy Majumder in Kathmandu.

 Officials admit they have been overwhelmed by the scale of the disaster, but highlight the challenges it poses in one of Asia's poorest countries. 
 
 "The government is trying its best to deliver the relief materials," National Disaster Management chief Rameshwor Dangal told the BBC. "The problem is the level of disaster is very high and it's spread over more than 20 districts." 
 
 Renaud Meyer of the UN Development Programme said Kathmandu's single-runway airport was struggling to accommodate the rush of aid flights, but teams were delivering supplies as quickly as possible. 
 
 On Mount Everest - where the quake triggered an avalanche that killed at least 18 people - all stranded climbers have now been evacuated from base camp.

– These are desperate times in Nepal, where officials say the death toll from Saturday's earthquake has now passed 5,000, but stories of hope are still emerging from the devastation. In Kathmandu, a French rescue team helped pull a survivor from the ruins of a building yesterday after he had spent more than 80 hours surrounded by dead bodies, Reuters reports. Rishi Khanal, 27, was on the second floor of the seven-story building when it collapsed. He "survived by sheer willpower," a doctor says. "I had some hope but by yesterday I'd given up," Khanal tells the AP. "My nails went all white and my lips cracked." Though he thought he would die, he continued to bang on rubble and drank his urine to survive. The United Nations says international teams have pulled 14 survivors from the rubble so far, the BBC reports. But for many of the 8 million people the UN says were affected by the quake, food and water is growing scarce. In a hard-to-reach district near the epicenter of the magnitude-7.8 earthquake, aid arrived for the first time today, the AP reports. A villager in Paslang, which has been almost completely destroyed, tells the AP that his pregnant wife's final act was to push their 5-year-old daughter to safety. "When I got home, there was nothing," soldier Bhoj Kumar Thapa says. "Everything was broken. My wife—she was dead." (Experts warn that aftershocks could continue for months.)
