More than 3,000 are missing after a massive flood hit northern Nepal and China’s Tibetan areas.

As rescue efforts in communities buried by catastrophic flash floods along the border between Nepal and China entered their fourth day on Saturday, authorities continued finding survivors and transporting them to safety.

Authorities are warning that a newly formed and overflowing lake could trigger further flooding in areas devastated by a catastrophic flash flood along the Himalayan border between Nepal and China.

Footage of the flash floods have become almost impossible to find on China’s heavily censored internet.

Authorities are closely monitoring a second newly formed lake as rescue efforts continue. Follow for live news updates.

Floodwaters swept away villages near the border between Nepal and the Tibet region of China, on Wednesday, leaving at least 160 people dead and hundreds missing across a 40-mile path of destruction. An initial assessment of satellite imagery indicates that a collapsing glacier may have caused the flooding. The death toll is expected to rise.

China has warned there is a "high risk" that a lake formed after the recent landslide near the Nepal-Tibet border may burst, causing a second flood downstream. The warning comes after Wednesday's deadly flash flood in the same area which scientists say was triggered by the collapse of a mountain glacier into a river.

China has suspended rescue efforts at the scene of a catastrophic mudslide on the Tibet-Nepal border after a lake formed by the disaster began overflowing, threatening to send a new torrent of debris downstream.

Videos posted by Tibetan locals on Chinese social media platforms showing the flash floods are reportedly being removed by the Xi Jinping-led regime. The censorship by the Chinese Communist Party has raised concerns that restricted access to information could hinder transparency and rescue efforts at a time when a catastrophe has already claimed more than 500 lives,
