Fighting erupted along the border between Thailand and Cambodia on Thursday, leading to a serious escalation of tensions that have simmered for over a century. Thai authorities have reported that at least 12 Thai nationals, many of whom were civilians, lost their lives. The situation remains murky regarding casualties on the Cambodian side.

The conflict reportedly began with an exchange of gunfire along the border, which Thailand claims was initiated by Cambodian forces. Following initial skirmishes, Thailand accused Cambodia of launching rocket attacks, prompting air strikes against Cambodian military targets.

The roots of this conflict can be traced back to the revision of borders after Cambodia's French occupation over a century ago, but the relationship turned hostile in 2008 when Cambodia sought to register an ancient temple in disputed territory as a UNESCO World Heritage Site. Since then, sporadic clashes have emerged, escalating tensions significantly after the killing of a Cambodian soldier in May. Protective measures have been introduced by both sides, with Cambodia implementing bans on several imports from Thailand, including fruits and vegetables.

On Thursday, divergent accounts of the events were reported. The Thai National Security Council (NSC) accused Cambodian forces of gathering heavy weaponry and initiating fire at Thai troops, compelling a defensive response. Conversely, Cambodian officials claimed the conflict began with Thai soldiers encroaching on sacred land and unilaterally opening fire.

Leaders from both nations have acknowledged the delicate nature of the dispute. Thailand's Acting Prime Minister Phumtham Wechayachai urged a resolution in accordance with international law, while Cambodian Prime Minister Hun Manet hinted at reluctantly engaging force in self-defense. Experts suggest past skirmishes have quickly de-escalated, although current leadership dynamics may hinder a swift resolution.

For travelers considering visits to the region, the fighting remains localized. The British Foreign Office has advised caution, particularly near tourist sites in the area, while China has encouraged its nationals in Cambodia to steer clear of the Thai border amid the escalating tensions.
