A 4-year-old girl in the northern mountainous province of Lao Cai was killed Tuesday after a landslide buried her kindergarten class.
Chu Thi Ha Ly died on the way to the hospital after being hit hard by the landfall.
Three other students and the teacher Pham Thi Hang, 26, were injured. While Hang broke her leg, one of the students broke his arm.
More than ten other students managed to escape.
Around a thousand cubic meters of land and rock fell from around a hight of 12 meters height, possibly due to continous heavy rain in recent days, authorities said.
The kindergarten had borrowed the office of a village cultural house in Bao Thang District to conduct its classes.
