Nepal estimates $4.78bn is needed to rebuild after deadly glacial floods killed 1,428 people and left more than 5,600 missing.

It's been more than 10 days since a glacial collapse sent freezing water, rocks and debris roaring down Nepal's Bhotekoshi and Trishuli valleys.

Nepal is expected to demand contributions towards the $5 billion it says it needs to help rebuild the country after the recent catastrophic floods.
