Thailand and Cambodia clashed for a fourth day Sunday, despite both sides saying they were ready to discuss a ceasefire after a late-night intervention by US President Donald Trump.
The neighbors, popular destinations for millions of foreign tourists, have been locked in their bloodiest conflict in years over the disputed border, with at least 33 people confirmed killed and more than 200,000 displaced.
Both said they were willing to start talks to end the fighting, after Trump spoke to the two prime ministers late on Saturday and said they had agreed to meet and “quickly work out” a ceasefire.
But fresh artillery clashes erupted on Sunday morning near two long-contested ancient temples in the frontier region between northern Cambodia and northeast Thailand that has seen the bulk of the fighting.
Cambodian defense ministry spokeswoman Maly Socheata said Thai forces began attacking areas around the temples at 4:50 am.
The regular thump of artillery rattled windows in the Cambodian town of Samraong, around 20 kilometers (12 miles) from the frontline, AFP journalists said.
Thai Army Deputy Spokesman Ritcha Suksuwanon said Cambodian forces began firing artillery around 4:00 am as the two sides battled for control of strategic positions.
Cambodian Prime Minister Hun Manet on Sunday said his country “agreed with the proposal for an immediate and unconditional ceasefire between the two armed forces”.
He said his Foreign Minister Prak Sokhonn will talk to US Secretary of State Marco Rubio to coordinate with the Thais, but warned Bangkok against reneging on any agreement.
After Trump’s call, Thailand’s acting Prime Minister Phumtham Wechayachai said he had agreed in principle to enter a ceasefire and start talks “as soon as possible”.
While both sides have expressed a desire for talks to end the crisis, neither has so far been willing to back down. On Sunday, they again each blamed the other for undermining peace efforts.
The Thai foreign ministry also accused Cambodian forces of firing shells into civilian homes in Surin province.
“Any cessation of hostilities cannot be reached while Cambodia is severely lacking in good faith and repeatedly violating the basic principles of human rights and humanitarian law,” the foreign ministry said in a statement.
From the Cambodian side, defense ministry spokeswoman Maly Socheata issued a statement denying that they fired first.
The statement accused Thailand of “deliberate and coordinated acts of aggression”.
A long-running border dispute erupted into combat this week with jets, tanks and ground troops battling in the rural border region, marked by a ridge of hills surrounded by wild jungle and agricultural land where locals farm rubber and rice.
Thailand says seven of its soldiers and 13 civilians have been killed, while Cambodia has confirmed eight civilian and five military deaths.
The conflict has forced more than 138,000 people to be evacuated from Thailand’s border regions, and 80,000 have been driven from their homes in Cambodia.
After an urgent United Nations Security Council meeting Friday in New York, Cambodia’s UN Ambassador Chhea Keo said his country wanted “an immediate ceasefire” and a peaceful resolution of the dispute.
As well as blaming each other for starting the fight, Cambodia has also accused Thai forces of using cluster munitions, while Thailand accused Cambodia of targeting civilian infrastructure, including hospitals.
The fighting marks a dramatic escalation in a long-running dispute between the neighbors over their shared 800-kilometre border where dozens of kilometers are contested.
