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.

Thailand’s cabinet approved the purchase of four Gripen fighter jets as part of a broader plan to modernize its military, days after its air force used the Swedish-made jets in a deadly border clash with neighboring Cambodia.

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.
