We’re closing this blog now as tensions between Cambodia and Thailand remain high following two days of border clashes that have displaced tens of thousands and drawn international concern. Here’s a summary of today’s key developments:

  • Thailand says it is open to talks. The country’s foreign ministry signalled it is ready to resolve the crisis diplomatically. “We are ready, if Cambodia would like to settle this matter via diplomatic channels,” spokesperson Nikorndej Balankura told AFP.

  • Clashes have erupted in at least 12 locations. A Thai military official said on Friday the violence spans a wide stretch of the disputed border area.

Thailand 'ready' for talks as international pressure for ceasefire mounts

Thailand’s foreign ministry has signalled it is open to diplomatic talks with Cambodia to end the current border clashes.

“We are ready, if Cambodia would like to settle this matter via diplomatic channels, bilaterally, or even through Malaysia, we are ready to do that. But so far we have not had any response,” foreign ministry spokesperson Nikorndej Balankura told AFP.

He added that there were signs the fighting was beginning to ease. Malaysia, who currently chairs the Association of Southeast Asian Nations (ASEAN), have previously called for a ceasefire.

The United States has also urged an “immediate” end to the conflict, while France, Cambodia’s former coloniser, has also called for a cessation of hostilities, according to AFP.

The European Union and China, a close ally of Cambodia, have also expressed concern about the violence and pressed both sides to seek dialogue.

Cambodia claims Thailand committing 'war crimes'

A spokesperson for Cambodia’s Ministry of National Defence has accused Thailand of committing war crimes, claiming the Thai military carried out airstrikes and used cluster munitions and heavy weapons at seven locations inside Cambodian territory.

According to Cambodian local media reports, Lieutenant General Maly Socheata said the attacks began at 8:46am on Thursday and included the use of F-16 fighter jets.

Earlier, we reported that Cambodia alleged that cluster munitions had been used in attacks which are banned in some instances under international law.

“These acts of aggression are both brutal and inhumane,” Maly said. “They violate international law, including the Convention on Cluster Munitions... and reflect a disregard for the most basic humanitarian norms.”

Cambodia’s defence ministry also claims it has repelled further attempts by Thai forces to advance near contested temples along the border.

There has been no immediate response from the Thai military.

The UK Foreign, Commonwealth and Development Office (FCDO) has issued travel advice, warning British nationals to avoid large swathes of territory on both sides of the Thailand-Cambodia border.

“We advise against all but essential travel to the affected border areas,” the FCDO said on Friday, citing reports of rocket and artillery fire along multiple locations.

In Cambodia, the FCDO now advises against all but essential travel within 50km of the border with Thailand in Oddar Meanchey and Preah Vihear provinces. Several tourist sites, including the Preah Vihear temple, Ta Krabey, and Ta Muen Thom temples, have been closed. The land border has also been suspended.

In Thailand, the warning applies to areas within 50km of the Cambodian border in Buriram, Si Saket, Surin, and Ubon Ratchathani provinces.

The FCDO also noted the presence of unexploded landmines in some areas and urged travellers to follow local security guidance closely.

The US, Australia and New Zealand, have also updated their travel advice to recommend avoiding areas where soldiers may be engaged in armed conflict.

Updated

The border crisis between Cambodia and Thailand is becoming “particularly combustible” due to a dangerous mix of nationalism, military posturing, and political fragility in both countries, a leading Southeast Asia expert has warned.

Michael Buehler, a reader in comparative politics at SOAS, University of London, told The Guardian that the tensions are “rooted in a century-old dispute over poorly demarcated colonial-era boundaries,” but the current escalation follows a series of flashpoints in recent months.

“Things deteriorated rapidly after a May skirmish that left a Cambodian soldier dead, followed by the controversial leaked call between Thai PM Paetongtarn Shinawatra and Cambodia’s former leader Hun Sen,” he said. “That moment not only exposed internal rifts in Bangkok but also publicly torched the historically close ties between the ruling families of both countries.”

The crisis deepened Wednesday when Thailand expelled Cambodia’s ambassador and recalled its own.

Fighting then broke out early Thursday and has since escalated from small-arms fire to heavy shelling across disputed stretches of the border.

“Cambodia, meanwhile, is pressing for an ICJ resolution, which Thailand resists, likely fearing a repeat of past rulings that favored Phnom Penh,” Buehler said.

“With both governments under pressure and national pride at stake, there’s a real risk of further deterioration,” Buehler added.

Tens of thousands of people have fled their homes as border clashes between Cambodia and Thailand entered a second day, stoking fears of a wider conflict.

Thailand’s health ministry said over 58,000 people have been evacuated to temporary shelters across four border provinces. Cambodian officials reported more than 4,000 displaced near Oddar Meanchey province.

Civilians on both sides have been caught in the crossfire. In Surin province, around 600 evacuees are sheltering inside a university gym. “I just heard, boom, boom,” said seamstress Pornpan Sooksai, who fled with her four cats told AP. “We already prepared the cages, clothes and everything, so we ran... I was frightened, scared.”

Rattana Meeying, who also fled Surin, compared the violence to the 2011 border clashes. “Children, old people, were hit out of the blue,” she said. “I never imagined it would be this violent.”

In Sisaket province, evacuations continued on Friday after fresh shelling damaged Phanom Dong Rak hospital and seriously injured at least three Thai soldiers.

Across the border, Cambodian villagers sought refuge in forest monasteries and dug makeshift underground shelters. “So that I can return to my home and work on the farm,” 74-year-old Veng Chin said, “I plead with both governments to negotiate a settlement.”

UN chief calls for restraint as security council to hold emergency meeting

António Guterres, the UN secretary general, has urged both Cambodia and Thailand to exercise restraint and resolve their escalating border dispute through dialogue, according to deputy spokesperson Farhan Haq.

The UN Security Council is expected to convene an emergency meeting on the crisis later today in New York.

We reported earlier that Malaysia, which currently chairs the ASEAN regional bloc that includes both countries, has also called for an immediate end to hostilities and reiterated its offer to mediate.

Prime Minister Anwar Ibrahim said earlier he had personally contacted both governments to urge a ceasefire and open space for diplomacy.

Cambodia has accused Thai forces of striking near the Preah Vihear temple – a UNESCO World Heritage site and longstanding flashpoint between the two countries.

Authorities in Phnom Penh released photos they say show damage to the ancient hillside temple complex, which sits along the contested border in Preah Vihear province.

They pledged to pursue international justice for what they described as a violation of heritage and sovereignty.

The Preah Vihear temple has been at the centre of previous conflicts, including deadly clashes in 2008 and 2011.

The International Court of Justice ruled in Cambodia’s favour in both 1962 and again in 2013, affirming its sovereignty over the temple and surrounding land.

Thailand rules out US and China efforts to help resolve dispute

Thailand has rejected offers of mediation from third countries in its ongoing border conflict with Cambodia, insisting the dispute should be resolved bilaterally.

Speaking to Reuters, Thai foreign ministry spokesperson Nikorndej Balankura said that while the United States, China, and Malaysia have all offered to facilitate dialogue, Bangkok is not seeking outside intervention at this stage.

“I don’t think we need any mediation from a third country yet,” Nikorndej said.

“We stand by our position that bilateral mechanism is the best way out, this is a confrontation between the two countries,” Nikorndej added.

The foreign ministry spokesperson went on to say that the Cambodian side must stop violence along the border first.

The PM’s office of Cambodia has just issued a statement with further details accusing Thailand of using cluster munitions.

In a post on X, the Cambodian Mine Action and Victim Assistance Authority (CMAA) said it “expresses its deepest alarm and strongest condemnation following reports that the Royal Thai Armed Forces deployed cluster munitions today, July 25, 2025, in a border area within the Cambodian territory.”

Preliminary reports from local authorities and demining teams claim that cluster munitions were used in Phnom Khmouch and Techo Thammachart Village – near the Thai border.

The first attack reportedly took place at 5.25am local time, with a second strike at 6.50am local time, putting civilians and deminers at immediate risk, it said.

CMAA described the incident as a “serious breach of international humanitarian norms”. Cluster munitions are banned under the 2008 Convention on Cluster Munitions due to their indiscriminate impact and lasting danger, particularly to children, the statement added.

Malaysian PM urges Cambodia and Thailand to ‘immediately implement ceasefire’

Malaysia’s Prime Minister Anwar Ibrahim has intervened in the escalating tensions along the Cambodia–Thailand border, calling for an “immediate ceasefire” and offering Malaysia’s assistance in facilitating dialogue between the two neighbours.

In a statement posted on Facebook, Anwar said he had spoken directly with Cambodian Prime Minister Hun Manet and Thailand’s Deputy Prime Minister Phumtham Wechayachai to voice Malaysia’s “concerns over rising tensions along the borders of the two countries”.

Speaking in his capacity as chair of the Association of Southeast Asian Nations (ASEAN) for 2025, Anwar said Malaysia was “ready to help and facilitate this process in the spirit of ASEAN unity and joint responsibility”.

“I appealed to both leaders to immediately implement ceasefire to avoid worsening conflicts and to open up space for peaceful dialogue and diplomatic solutions,” he wrote.

The Malaysian premier welcomed what he described as “positive gestures and willingness shown by Bangkok and Phnom Penh” in response to his appeal, though he did not elaborate on the nature of those gestures.

“I firmly believe that ASEAN’s strength lies in its solidarity,” he added. “Peace must always be our undivided collective choice.”

Opening summary

Hello and welcome to our live coverage of the clashes along the border of Thailand and Cambodia.

Thailand’s military has accused Cambodia of using of long-range weapons to “target civilian areas” and of committing “barbaric acts” that “have senselessly claimed the lives and inflicted injuries upon numerous innocent civilians” as the two countries exchange fire for a second day.

Phnom Penh’s landmine authority has, meanwhile, accused Thailand of using cluster munitions, calling it a “serious violation of humanitarian norms”.

Thai authorities say 15 people have so far been killed, including 14 civilians, while a Cambodian official said one civilian had been killed, although the Cambodian government has yet to give any official update on casualties.

The long-running border dispute erupted into intense fighting with jets, artillery, tanks and ground troops on Thursday after weeks of tensions. More than 100,000 Thais have fled the fighting, Bangkok said on Friday.

We’ll bring you more on that soonest. In other developments:

  • Britain’s foreign ministry advised against all but essential travel to parts of Cambodia and Thailand, both popular destinations for foreign tourists, after the fighting.

  • Fighting was focused on six locations, the Thai army said on Thursday. Six Thai air force jets were deployed, hitting two “Cambodian military targets on the ground”, according to Thai military deputy spokesperson Ritcha Suksuwanon.

  • Cambodia has not yet commented on casualties on its side. Defence ministry spokeswoman Maly Socheata refused to answer when asked about the issue at a news conference.

  • Both sides blame the other for starting the fighting. On Wednesday, Thailand had expelled the Cambodian ambassador and recalled its own envoy after five members of a Thai military patrol were wounded by a landmine.

  • Cambodia downgraded ties to “the lowest level” on Thursday, pulling out all but one of its diplomats and expelling their Thai equivalents from Phnom Penh.
