A bus with 20 passengers has been swept away into a flooded watercourse due to a landslide in northern Vietnam.
The rescue efforts are being hindered by the landslide, whose stones and mud are blocking access to the accident site.
In several rivers in the northern parts of the country, the water level is alarmingly high, the authorities warn. In Phu Tho province, a bridge over the flooded Red River has collapsed. About a dozen cars and trucks, as well as two motorcycles, are reported to have fallen into the river, resulting in many missing persons.
Typhoon Yagi, which reached Vietnam on Saturday, is the strongest typhoon to hit the country in decades. On Sunday, the winds died down, but the continued rainfall is putting a severe strain on the already heavily burdened infrastructure.
The typhoon has also caused fatalities and extensive damage in the Philippines and southern China.
Climate change is said to be leading to increasingly intense tropical storms, such as Yagi, as warmer sea water fuels the storms and causes faster winds and heavier rainfall.
