Five villagers were killed by a lightning strike on Thursday during a torrential rain in southwestern Cambodia's Koh Kong province, according to the National Police's website.

The incident took place at 3:00 p.m. local time in Prolay village of Thmor Baing district when the victims, including two women, were constructing a wooden house under the rain, the website said.

"Five people were killed immediately and another one got injured by the lightning strike," Koh Kong Provincial Governor Mithona Phouthorng was quoted as saying.

Lightning occurs every year in Cambodia, particularly in the rainy season from May to October.

In 2017, at least 80 Cambodians, mostly rural residents, were killed by lightning strikes and 63 others injured, according to the National Committee for Disaster Management.
