A Cambodian soldier was killed when Thai and Cambodian troops briefly fired at each other in their disputed border area on Wednesday, officials said.

Cambodian army spokesperson Mao Phalla said the troops were conducting a routine patrol along the border when the Thai side opened fire. 

The Thai army said the Cambodian soldiers entered a disputed area and Thai soldiers approached the area to negotiate but due to misunderstanding, the Cambodian side opened fire and the Thai soldiers then retaliated.
