By Gopal Sharma KATHMANDU, May 3 (Reuters) - Three people were pulled out alive from the rubble of their home eight days after Nepal's devastating earthquake, an official said on Sunday, but rescuers have found about 50 bodies on a popular trekking route that was hit by an avalanche. The current toll of 7,056 dead is likely to rise as an entire village was carried away by the avalanche and many more people are believed to have died, officials said.
