Thailand and Cambodia signed a ceasefire Saturday to end weeks of border fighting that killed dozens and displaced nearly 1 million civilians.

Thailand's army on Monday (Dec 29) accused Cambodia of violating a newly signed ceasefire agreement, reached after weeks of deadly border clashes, by flying more than 250 drones over its territory.

In an agreement signed on Dec 27, both countries agreed that civilians residing in the affected border areas can return to their homes.
