A total of 75 people were also injured by lightning strikes last year, while 49 cows and buffaloes were killed by the naturally occurring electrical discharge, Keo Vy, spokesman of Cambodia's National Committee for Disaster Management, told Kyodo News.
In 2012, he said, 103 Cambodians were killed by lightning, and 71 were injured, while 34 head of cattle were killed.
Most of the victims were living in rural areas.
Keo Vy blamed the outbreak of fierce lightning on climate change.
Lightning occurs every year in Cambodia, especially in the rainy season that lasts from May through October.
