The death toll climbed to over 4,350 on Tuesday with more than 8,000 others injured, as Nepal Prime Minister Sushil Koirala admitted that the rescue and relief operations have not been effective.

Hundreds of people are still trapped under tonnes of rubble in the capital Kathmandu and some of the worst-affected remote mountainous areas amid concerns that toll could cross 5,000 mark, authorities said.
