Nepal quake: Towns near epicentre 'devastated' - Red Cross
Towns and villages near the epicentre of Saturday's earthquake in central Nepal have suffered "almost total devastation," the Red Cross says, the BBC reported.
Assessment teams say they have found survivors in a "desperate situation."
More than 6,000 people are now known to have died in the 7.8-magnitude quake but the fate of thousands more in many remote areas remains unknown.
The government has warned that the death toll could rise to more than 10,000.
Although rescue teams from Nepal and the international community are operating in the capital Kathmandu and the surrounding area, landslides and poor weather have hampered efforts to reach isolated districts.
Emergency aid has also yet to reach many of the worst-hit areas, six days after the quake hit.
There was some good news on Thursday when a 15-year-old boy and a woman in her 20s were pulled from the wreckage of two collapsed buildings in Kathmandu.
But the BBC's Sanjoy Majumder in the city says there is growing anger at the government's response to the disaster, with a number of protests breaking out.
