A UXO explosion left a 22-year-old man in critical condition in Kampong Thom’s Kampong Svay district on Sunday. District police officials said yesterday that the explosion occurred as the man was tinkering with the device, assuming that it had previously detonated. Seng Ly, Kampong Svay district police chief, said Touch Nhouch, 22,  had sustained serious injuries to his stomach after being struck by the explosion when he spotted the UXO in a rice field in Damrei Slap commune while tending to his water buffalo. He added the victim was receiving medical treatment in the Kampong Thom provincial hospital.
