A ceasefire between Cambodia and Thailand appears to be holding, hours after it came into effect at midnight local time (1 p.m. ET Monday), following days of clashes across the two countries’ disputed border.

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.

Thai and Cambodian leaders are meeting in Malaysia in an urgent effort to resolve deadly border clashes that entered a fifth day despite mounting international calls for peace.
