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.

Thailand has accused Cambodia of "deliberately" violating a ceasefire the two countries had agreed on Monday to end border clashes that have killed at least 33 people and displaced thousands. It's a shaky start for the ceasefire, which was meant to bring an end to five days of bombardment and rocket attacks along their shared border.

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