Rescue and relief efforts in Nepal and Tibet have been hampered this Sunday by heavy rain and rising river levels. The latest figures following Wednesday’s flash floods put the death toll at 750, while more than 3,000 people remain missing. Nepal’s disaster authorities are urging rescue teams to “exercise caution”, warning that bad weather, swollen rivers and the threat of further flooding could hamper operations.
