PUTRAJAYA, Malaysia (AP) — 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 leaders of Cambodia and Thailand agreed to a ceasefire in a bid to bring an end to their deadliest conflict in more than a decade.

Thailand’s military accused Cambodian forces on Wednesday of breaching a ceasefire agreement at three separate locations along the disputed border, warning that continued aggression could compel Thai forces to respond more decisively.
