Khmer Rouge guerrilla forces routed troops of the Vietnamese-backed Cambodian government in two battles, the guerrilla radio reported Wednesday.

The radio said its troops faced government forces including 1,200 Vietnamese soldiers who attempted to attack Khmer Rouge-held areas near the Thai border on Sunday."Our national resistance forces killed 50 of these Vietnamese enemy soldiers, with 12 bodies left on the battlefield, and wounded 20 others, " it said.
