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.

As part of the cease-fire deal, military commanders from both sides will hold talks Tuesday to defuse tensions while Cambodia will host a border committee meeting on Aug. 4.
