Cambodia and Thailand have agreed to an “immediate and unconditional ceasefire” beginning at midnight local time (1 p.m. ET Monday), following days of clashes across the two countries’ disputed border.

The fighting, which began last Thursday after a land mine explosion injured Thai soldiers, has killed at least 35 people and displaced over 260,000 people.

Cambodia and Thailand are meeting Monday in Malaysia for talks to end days of deadly fighting over their disputed border.
