Thailand has launched air strikes along its disputed border with Cambodia after both sides accused each other of violating a US-brokered ceasefire. The Thai military confirmed on Monday that the escalation followed Cambodian fire on its troops stationed in Ubon Ratchathani province.

According to the Thai army, at least one soldier was killed and four others were wounded in the renewed clashes. Officials said Thai aircraft were now targeting “military positions in several areas” in response to the attack.
Cambodia’s defence ministry, however, accused Thailand of initiating the latest round of hostilities with dawn assaults on two Cambodian positions. It said its troops had exercised restraint and avoided retaliatory fire despite what it called “provocative actions.”

Thai authorities claimed that Cambodia fired BM-21 rockets towards civilian zones, though no casualties were reported. The exchange marks the most serious breach since the July conflict, which forced around 300,000 people to flee and left at least 48 dead.
The two neighbours had agreed to halt fighting under a ceasefire arranged by Malaysian Prime Minister Anwar Ibrahim and endorsed by US President Donald Trump. However, tensions resurfaced last month after a landmine explosion seriously injured a Thai soldier, prompting Bangkok to suspend the pact.

Former Cambodian leader Hun Sen blamed Thailand for provoking conflict, calling its forces “aggressors” attempting to trigger retaliation. He urged Cambodian soldiers to maintain discipline and abide by the “red line” set for military response.
In Thailand, more than 385,000 civilians across four border districts are being evacuated as the situation deteriorates. The military reported that over 35,000 people have already been moved to temporary shelters for safety.
