Villagers are helped to cross a swollen river in Vietnam with the help of an excavator as a tropical storm caused heavy flooding.

Footage captured on August 17 in Son La province shows a gushing river caused by tropical storm Bebinca, which hit Thailand, Vietnam and Laos this weekend.

Villagers are seen climbing out of the excavator's digger in order to cross the river.

The storm and subsequent flooding caused at least 21 homes to collapse.
