Landslides triggered by heavy rains from a tropical storm have killed at least seven people in northern Vietnam.

The chief administrator of Lang Son province's Cao Loc district, Hua Anh Tuan, says six people were killed and five others were injured when a landslide buried the hut they were sleeping in early Wednesday. A 5-year-old girl was killed and her mother was injured when another landslide struck their house.

Tropical Storm Kalmaegi was downgraded from a typhoon when it struck northern coastal Vietnam on Tuesday night. About 55,000 people in four northern coastal provinces were evacuated ahead of the storm.

The typhoon slammed into the northern Philippines on Monday, unleashing flooding and killing at least two people.
