HANOI, April 27 (AFP) - A landslide triggered by heavy rains has killed three children in their sleep in Vietnam, an official said Tuesday.
The children, all between two and 10 years old, were buried when a massive rock fell on their house in the northern province of Ha Giang on Monday night.
A search is ongoing for the mother and another nine-year-old boy, local district official Nguyen Thi Duoc said, adding that the family was from the Hmong ethnic minority.
Hundreds of people die every year in Vietnam as a result of landslides, heavy rains, floods and typhoons.
The monsoon usually hits the country between July and November, but strong rains at other times of the year also sometimes cause landslides, particularly in remote mountainous areas.
