Nepalis spend third night in open as quake toll passes 4,000

Hundreds of thousands of Nepalis spent another night in the open after a massive quake which killed more than 4,000, as officials warned the final toll could rise sharply once rescuers reach cut-off areas.

With fears rising of food and water shortages, Nepalis were rushing to stores and petrol stations to stock up on essential supplies in the capital Kathmandu, left devastated by Saturday's 7.8-magnitude quake.

Officials say more than 4,100 people are now known to have died, including 4,010 in Nepal - making it the quake-prone Himalayan nation's deadliest disaster in more than 80 years.

More than 90 people have been killed in neighbouring India and China while a further 7,500 people were injured in Nepal.
