Thailand has since accused Cambodian troops of violating the ceasefire multiple times, a charge denied by authorities in Phnom Penh, who instead allege that the Thai military has wrongfully detained a number of its soldiers.

A fragile truce between Cambodia and Thailand held for a second day on Wednesday, despite mutual accusations of violations, and Cambodia took military attaches and diplomats to a border checkpoint destroyed by fighting to verify the ceasefire.

Cambodia on Thursday requested Malaysia to intervene to "swiftly" secure the release of its soldiers in the Thai army's custody.
