A huge flash flood and landslide hit the Himalayan border between Nepal and Tibet, killing and stranding people on both sides.

• A landslide swept down from the Nepali side and destroyed the inspection building at the Gyirong crossing, leaving people no time to escape.
• Nepal has reported at least 16 dead and hundreds of tourists out of contact.
• China has not yet released casualty numbers, and the road to the crossing is cut off.
• Taiwan's Mainland Affairs Council says 51 of its citizens are registered as being in Tibet and is trying to confirm they are safe.
• Taipei has passed on condolences to Beijing and opened an emergency hotline for families.

Outlook: The death toll is likely to climb as rescuers reach the cut-off crossing and China releases its own figures.
