A glacier collapse on the Nepal-Tibet border set off flash floods and landslides that have killed more than 470 people, with over 1,500 still missing.

• Ice, rock and debris crashed into Himalayan river valleys on Wednesday, wiping out communities on both sides of the border.
• The death toll has climbed past 470 across Nepal and Tibet, and rescue teams are still searching for more than 1,500 missing people.
• The disaster was first blamed on an earthquake because the collapse shook the ground, but later checks pointed to a glacier and rock collapse.
• Taiwan's President Lai Ching-te sent public condolences to the families of the dead and wished for a fast, safe recovery.

Outlook: The death toll is likely to rise as rescuers reach cut-off valleys, and the collapse will add to worries about melting Himalayan glaciers.
