Others have come forward describing the terror of the mudslides and flooding that tore through the area.

For context, a torrent of floodwater, mud and debris bulldozed through the Tibetan border washing away villages, roads and critical infrastructure.

Notably, the mudslide that struck Tibet's Gyirong county is almost 1.5m deep with the edge stretching 2.5km from the border crossing.

This "significantly hinders subsequent rescue efforts", state broadcaster CCTV report authorities saying.

Helicopters applied in the rescue effort have struggled to land in some of the worst-hit areas as river levels are far higher than usual.

In Nepal's Rasuwa district, one of the hardest-hit areas, footage demonstrates bridges cracking apart and being swept away entirely by the sheer force of the floodwaters.

In practice, a local health worker in the region described the scene as utter devastation.
