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 U.N. ambassador told a Security Council meeting on Friday that soldiers had been injured by newly planted land mines in Thai territory on two occasions since mid-July - claims Cambodia has strongly denied - and said Cambodia had then launched attacks on Thursday morning.
