Thailand and Cambodia agreed Monday to an unconditional ceasefire during a meeting in Malaysia, in a significant breakthrough to resolve five days of deadly border clashes that have killed dozens and displaced tens of thousands.

The Thai army accused its Cambodian counterpart of violating the ceasefire, which was intended to end a fierce five-day border conflict.

Thailand and Cambodia have agreed to an "immediate and unconditional ceasefire" after five days of fighting at their border killed at least 33 people and displaced tens of thousands.
