Thailand has accused Cambodia of "deliberately" violating a ceasefire the two countries had agreed on Monday to end border clashes that have killed at least 33 people and displaced thousands. It's a shaky start for the ceasefire, which was meant to bring an end to five days of bombardment and rocket attacks along the shared border.

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.
