A violent rainstorm destroyed 20 houses and killed one cow on Tuesday night in three communes across Kampong Cham’s Cheung Prey district, police said yesterday. Heng Vuthy, Cheung Prey district police chief, said that 10 houses were completely destroyed while another 10 were badly damaged, largely because the houses were fragile structures made of palm trees. Heng Vuthy added that provincial Red Cross officials would bring rice and other supplies to the area today to support the families that were affected by the storm.
