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 the Thai military claimed they struck a facility storing rocket systems.
This month’s hostilities have resulted in at least 21 fatalities in Thailand and 17 in Cambodia, displacing around 800,000 people.
The Cambodian defence ministry stated that the Thai forces targeted Poipet municipality around 11:00 am (0400 GMT) Thursday.
Shortly after, Thai Air Force spokesman Air Marshal Jackkrit Thammavichai confirmed that the military attacked a centre used to store BM-21 rockets, asserting no civilians were harmed.
The bombings mark a worrying turn for Poipet, a hub for Thai gamblers and a vital border checkpoint.
On Tuesday, Thailand noted that between 5,000 and 6,000 of its nationals remain stranded in Poipet due to Cambodia’s closure of land border crossings.
The Cambodian interior ministry justified the border closure as a necessary measure to protect civilians, while advising that air travel remains an option for those wishing to exit.
This recent escalation follows a turbulent history between the neighboring nations, including a ceasefire brokered by international leaders that has since collapsed.
In the past week, accusations and counteraccusations have surged, with Thailand also being accused of bombing areas in Siem Reap province for the first time in this latest bout of conflict.
