The two nations have been locked in a decades-long conflict over their contested border. Tensions in disputed territories soured earlier this year.

Tensions have bubbled between the two neighbors for months, flaring on Thursday as Cambodia and Thailand exchanged fire.

The conflict between Thailand and Cambodia escalated into rare armed exchanges, involving artillery and airstrikes, resulting in civilian casualties. The dispute involves a long-standing debate over the sovereignty of the border.

Thailand and Cambodia traded accusations of fresh attacks Saturday as deadly border clashes entered a third day and President Donald Trump joined a chorus of international voices calling for a ceasefire.
