As rescue efforts in communities buried by catastrophic flash floods along the Nepal - China border entered their fourth day Saturday, authorities were still finding survivors and transporting them to safety. At relief centers, while some arrived, families of others waited anxiously for news of their loved ones as the death toll and the number of people unaccounted for continued to rise.

In a still-unfolding disaster, verified videos showed dozens of people swept away at the border.

The disaster is linked to climate change, with experts noting the region's vulnerability to extreme weather.
