DHAKA, July 25 (Xinhua) -- Two major incidents of rain-triggered mudslides have claimed five lives including four children in Bangladesh's Cox's Bazar district, some 292 km southeast of Dhaka, police said on Wednesday.

The children, three girls and their only brother, were buried alive after huge chunks of mud collapsed on their house on the slope of a hill, Farid Uddin Khandaker, a police officer in Cox's Bazar, told journalists.

The children's mother narrowly survived the mudslides that occurred at about 6:00 a.m. local time when the children were asleep, he said.

A body of a woman was recovered from another place in the district, he added.

Many dwellings in places of the district and elsewhere in the country were also reportedly damaged in rain-triggered landslides that are frequent in Bangladesh's hilly areas during monsoon seasons.

At least 153 people were reported killed and hundreds of others injured in the landslides that devastated five districts in Chittagong Hill Tracts in southeastern Bangladesh in June last year.
