Thailand says it has bombed a logistics centre near the Cambodian town of Poipet, known for being a major casino hub and the biggest land crossing between the two countries.
The bombings come as renewed border clashes show no sign of abating.
Cambodia's defence ministry reported that Thai forces dropped two bombs, while Thailand claimed that they targeted a facility storing rocket systems.
The renewed fighting this month has resulted in at least 21 fatalities in Thailand and 17 in Cambodia, with around 800,000 individuals displaced.
According to a statement from the Cambodian defence ministry, Thai forces targeted the Poipet municipality at around 11:00 am (0400 GMT) on Thursday. The Thai Air Force spokesman confirmed the attack, stating it targeted a site associated with BM-21 rockets, asserting that no civilians were harmed.
BM-21 rockets are typically fired in volleys from armored vehicles, demonstrating the escalation in military capability observed in recent months.
It marks the first time Poipet, a popular destination for Thai gamblers, has been bombed amidst the ongoing conflict.
On Tuesday, reports indicated that between 5,000 and 6,000 Thai nationals were stranded in Poipet after Cambodia shutdown its land crossings. The Cambodian interior ministry described the closures as necessary to mitigate civilian risks, while highlighting air travel as an alternative for those wishing to exit.
This border conflict, which has historical roots spanning over a century, intensified when Cambodian forces launched a rocket barrage into Thailand on 24 July, leading to retaliatory airstrikes by Thailand and a five-day clash resulting in numerous casualties.
Subsequently, a ceasefire was brokered by Malaysian Prime Minister Anwar Ibrahim and US President Donald Trump, yet hostilities reignited last week. Each nation accuses the other of provoking the renewed fighting, which has resulted in airstrikes and exchanges of artillery fire.
While Trump declared he could resolve the conflict with a mere phone call, both nations seem entrenched in their positions.
Adding to the tensions, Cambodia recently accused Thai forces of bombing Siem Reap, the site of the famous Angkor temples, highlighting a troubling expansion of violence across the region.
