NEPAL - Four South Africans are among the hundreds of tourists who have gone missing after devastating flash floods hit Nepal's border with China.
At least 31 people have died on both sides of the Nepal-China border.
An earthquake may have triggered the landslides, followed by floods which swept away bridges, roads and homes.
