Thailand said it launched airstrikes into Cambodia on Monday as fighting broke out in multiple areas along their disputed border, after both countries accused the other of breaching a ceasefire brokered by U.S. President Donald Trump, Reuters reports.
At least one Thai soldier had been killed and eight were wounded in the fresh clashes that intensified around 5:00 a.m. local time (2200 GMT), a Thai army spokesperson said, adding that air support was called in to hit Cambodian military targets.
Thailand's Air Force said that Cambodia mobilised heavy weaponry, repositioned combat units and prepared support elements that could escalate military operations.
"These developments prompted the use of air power to deter and reduce Cambodia's military capabilities," it said in a statement.
Cambodia's defence ministry said in a statement that the Thai military had launched dawn attacks on its forces at two locations, following days of provocative actions, and added that Cambodian troops had not responded.
Cambodia's influential former longtime leader Hun Sen, father of current premier Hun Manet, said Thailand's military was "aggressors" seeking to provoke a retaliatory response and urged Cambodian forces to exercise restraint.
"The red line for responding has already been set," Hun Sen said on Facebook, without elaborating. "I urge commanders at all levels to educate all officers and soldiers accordingly."
Three Cambodian civilians have been seriously injured in the fighting so far, according to a senior provincial official. Cambodia's defence ministry said its forces had not retaliated.
A simmering border dispute between the countries erupted into a five-day conflict in July, before a ceasefire deal brokered by Malaysian Prime Minister Anwar Ibrahim and Trump, who also witnessed the signing of an expanded peace agreement between the two countries in Kuala Lumpur in October.
