FLOODING triggered by a tropical storm has killed at least 20 people and left more than a dozen missing in northern Vietnam.

Ten people drowned in floods caused by heavy rain in Yen Bai province after Tropical Storm Son Tinh hit the country’s northern region last week.

In Thanh Hoa province, a flash flood swept through a village in Lang Chanh district and carried away a dozen stilt houses.

Local Luong Van Hung said: “The floods came so quickly and gave us so little time to escape. Some managed to run to high ground, but others were swept away.”

The floods took away a family of four as they were sleeping, said Nguyen Xuan Hong, chairman of Lang Chanh district.

Two people were found dead in the debris left by the flooding while the body of the family’s five-year-old daughter was recovered in a stream two miles from their home.

A rescue group of 300 people were looking for the fourth member of the family, who is still missing.

Casualties were also reported in Phu Tho, Lao Cai, Hoa Binh and Son La provinces, where heavy rain caused landslides and cut off roads. The rain stopped over the weekend, but the weather agency said another tropical depression is heading to the area this week.
