Since the exchange of fire began, Thailand has ordered the closure of its entire 817km border with Cambodia, and several countries, including Australia, New Zealand, Singapore, China, Hong Kong, the US, and the UK, have warned against travelling to the areas nearby.

The State Department raised both advisories to Level 2 on July 25, citing the “risk of unrest” in Thailand and crime and landmines in Cambodia.

Following border conflict that killed dozens of people, Thailand and Cambodia agreed to an "immediate and unconditional ceasefire" on Monday.
