The ceasefire reached in Malaysia was supposed to take effect at midnight on Monday, but it was quickly tested as Thailand and Cambodia continued to accuse each other of violating the truce agreements.

Cambodia has welcomed the return of two wounded soldiers captured by the Thai army. Their capture came after a ceasefire ended five days of combat over disputed territory.

Thailand's army sent home two Cambodian soldiers from a group of 20 on Friday, ahead of a key meeting in Malaysia next week where defence ministers and military commanders will hold talks aimed at maintaining a ceasefire along their disputed border.
