  2. How the border dispute led to Thailand's most recent political crisispublished at 09:10 GMT 9 December 2025

    It started with a phone call meant to calm rising border tensions, and ended with the downfall of one of Thailand's most powerful political dynasties.

    In June, Thailand's then-prime minister Paetongtarn Shinawatra found herself the target of heated public backlash after her phone call with Cambodia's former strongman leader Hun Sen was leaked.

    The Shinawatras and Hun Sen enjoyed famously a close friendship.

    In the audio clip, leaked by Hun Sen himself, Paetongtarn can be heard calling him "uncle" and criticising a Thai military commander.

    It took place against the backdrop of souring bilateral ties amid the border dispute, and Paetongtarn defended her tone as a negotiation tactic.

    But the uproar it caused eventually led to her dismissal in August - weeks after deadly border clashes killed dozens of soldiers and civilians.

    Paetongtarn Shinawatra ascension to Thailand's premiership in 2024 was seen as a stunning comeback for the Shinawatra dynasty - but her fall from grace has derailed the dynasty.

  3. 'No point' for Cambodia to violate ceasefire, says Cambodian expertpublished at 09:01 GMT 9 December 2025

    Thailand and Cambodia have both accused each other of initiating this latest round of clashes, in violation of a ceasefire that was brokered by US President Donald Trump in July.

    That ceasefire was always on shaky ground, Chhengpor Aun from the Cambodian think tank Future Forum tells the BBC's Newsday programme.

    But Aun suggests "there is no point for Cambodia to violate the peace agreements".

    "For the Cambodian side [the ceasefire] was seen as a win, because Cambodia, as a smaller country with a smaller military [and] smaller economy, would also want to seek a peaceful resolution to this conflict," says the Phnom Penh-based Aun.

    "We may not be able to independently verify who actually started and shot the first fire yesterday," he added. "But the contact matters, because in Cambodia there is no need to violate and tear down that peace agreement - but in Thailand that peace agreement is very unpopular. And the [Thai] prime minister has an election to run in the coming months."

    As violence escalates in Thailand's north-eastern borderlands, 150km away in the capital Bangkok, the Southeast Asian Games officially opened on Tuesday.

    Running from 9 December to 20 December in the capital and the nearby coastal province of Chonburi, the Sea Games features thousands of athletes from 11 South East Asian countries competing in events such as football, fencing, sailing and combat sports.

    This week's fresh border clashes have led to security being tightened for athletes, among whom are multiple Olympic gold medallists.

    Cambodia withdrew about half of its athletes from the Sea Games last week, pulling out of eight events including football, wrestling, judo and karate on the basis of safety concerns.

    Thailand's deputy Prime Minister Thammanat Prompao said on Tuesday that Thailand would "ensure the highest level of security" for Cambodian athletes, including the deployment of security personnel.

  5. Cambodia accuses Thailand of firing 'indiscriminately' into civilian areaspublished at 08:36 GMT 9 December 2025

    Cambodia's ministry of information has put out a statement accusing the Thai army of "indiscriminately firing" artillery into a "densely populated civilian town" in the border Pursat province.

    The statement condemned what it called the "inhuman and brutal act" and said this was one more instance of Thailand violating the ceasefire that was brokered in July and ceremonially ratified in October with US president Donald Trump.

    Both sides have accused each other of violating the ceasefire and provoking the latest conflict.

  6. Calls for Asean to help resolve 'very alarming' conflictpublished at 08:18 GMT 9 December 2025

    Fresh clashes at the Thai-Cambodia border as "very alarming", says Sothirak Pou, distinguished senior advisor to the Cambodian Center for Regional studies,

    Pou suggests that Asean could intervene to help resolve the conflict, noting that Malaysian Prime Minister Anwar Ibrahim, the bloc's regional chair, "is ready to offer good mediation, as he did before".

    "It is very confusing at the moment, and I think the longer without mediation from outside, the deeper the conflict will erupt," Pou says

    "But for the Cambodian side, we want peace, we want negotiation, we want to talk. We do not wish to have these conflicts."

  7. Where are the clashes happening?published at 08:04 GMT 9 December 2025

    Here's a map to situate where the clashes between Thailand and Cambodia are happening.

    Since Monday night, skirmishes have expanded to Thailand's Surin, Buri Ram,Sa Kaeo and Trat provinces, and Cambodia's Banteay Meanchey and Pursat provinces.

    Both sides have accused each other of targeting civilian locations, while claiming their own adherence to international law.

    This follows each country having accused the other of starting the violence on Monday.

    Thailand said its troops had responded to Cambodian fire in Thailand's Ubon Ratchathani Province, including by launching air strikes along the disputed border, while Phnom Penh's defence ministry said it was the Thai forces that attacked first, in Cambodia's Preah Vihear province.

  8. What is the Thailand-Cambodia border dispute all about?published at 07:46 GMT 9 December 2025

    This dispute dates back more than a century, to when the borders of the two countries were drawn after the French occupation of Cambodia.

    When Cambodia tried to register an 11th Century temple in the disputed area as a Unesco World Heritage Site in 2008, it was met with heated protest from Thailand.

    Over the next several years, those tensions would erupt into sporadic skirmishes at the border, which killed and wounded soldiers on both sides.

    Before this week's clashes, more than 40 people were killed in heavy fighting in July, sparked by the death of a Cambodian soldier in a border clash.

    As fighting continued for a third day along the Thailand-Cambodia border, a Cambodia-based academic has asked: “Where is the US?”

    Sothirak Pou, distinguished senior advisor to the Cambodian Center for Regional Studies, tells the BBC that the international community - including Asean, the UN, and allies of both countries - do not want to see continued military confrontation.

    US President Donald Trump helped end a deadly flare-up in July by calling leaders of both nations by phone. In October, he witnessed the signing of a "peace deal" between the two countries.

    “I wish that President Trump would call again, if at all possible. If he does, it will be effective in my view."

    The Royal Thai Air Force has confirmed more airstrikes on Tuesday, but declined to give details of the operation.

    Thailand began launching airstrikes at “military targets in several areas” on Monday in what it said was a counter to Cambodian attacks.

  11. Ceasefire 'not working', Thai foreign minister tells BBCpublished at 07:08 GMT 9 December 2025

    The ceasefire between Thailand and Cambodia is "not working", Bangkok's foreign minister Sihasak Phuangketkeow has told the BBC, as he accused Cambodia of breaching the deal.

    If the US were to continue to get involved, he says Thailand needs its help to seek "genuine peace and not just something on a piece of paper". US President Donald Trump had witnessed the signing of a "peace deal" between the two nations in October.

    Sihasak says there is little space for diplomacy unless Cambodia changes its actions. "And if they're willing to do so, then of course we can think of the best way forward."

    "The ball is in Cambodia's court, to come around, assume accountability, take responsibility, and then we can go from there," he says.

    Thitinan Pongsudhirak, a professor of international relations at Bangkok's Chulalongkorn University, says that these recent clashes on the Thai-Cambodia border have pushed the neighbouring countries back into a cycle of "spiralling, escalating violence".

    Nationalistic emotions are likely fuelling the conflict, he said.

    "Both governments have their own incentives and vested interests to pursue this military course of action, because they have domestic issues at home on both sides," Mr Thitinan told BBC Newsday.

    "On the one hand Cambodia has been revealed as the scam centre network of the region – a lot to answer for," he said. "On the Thai side, there is a lot of issues: the Anutin government is a minority government, it’s weak, it’s just mismanaged the floods in the south."

    With elections upcoming for Thailand early next year, Mr Thitinan suggested that Anutin is likely hoping to ride the nationalistic fervour into the polls "and emerge after with another premiership".

    US President Donald Trump has called on both Thailand and Cambodia to "fully honour" a ceasefire that was struck in July.

    "President Trump is committed to the continued cessation of violence and expects the governments of Cambodia and Thailand to fully honour their commitments to end this conflict," an official, who spoke on the condition of anonymity, told news agency Reuters.

    In July, the century-old border dispute between the South East Asian nations dramatically escalated with a Cambodian rocket barrage into Thailand, followed by Thai air strikes.

    Days later, both countries agreed to an "immediate and unconditional ceasefire" after Trump threatened to stop all negotiations on reducing US tariffs unless the two countries agreed to stop fighting.

    In October, both sides signed a ceasefire agreement, with Trump claiming a historic achievement in ending the conflict.

  15. Thailand says Cambodia firing rockets into civilian areaspublished at 05:55 GMT 9 December 2025

    Thailand's military has accused Cambodia of using multiple-launch rocket systems, bomb-dropping drones and kamikaze drones against Thai soldiers, with some rockets reportedly hitting civilian areas.

    The latest update issued by the 2nd Army Area Operations Center on Tuesday morning further noted that a total of 492 temporary shelters had been established across four border provinces in Thailand, accommodating 125,838 people.

    The Thai public has been asked to refrain from sharing photos, video clips, and information regarding troop movements or military operations, "in order to safeguard frontline personnel and maintain the effectiveness of our operations".

    "The 2nd Army Area will continue to employ all necessary measures to ensure national security, safety, and the protection of Thailand’s sovereignty to the fullest extent," the military statement said.

  20. Thailand accuses Cambodia of targeting civilianspublished at 03:53 GMT 9 December 2025

    A spokesperson for Thailand's ministry of defence has stressed that the country's military actions adhere to international humanitarian law, and that the protection of civilians is a high priority.

    "This stands in stark contrast to the weapons used by the Cambodian forces, which have caused harm to civilian lives and property," Rear Admiral Surasan Kongsiri has told a press briefing on Tuesday morning.

    "Thai operations focus solely on military targets to... reduce the ability of the Cambodian military capabilities, while Cambodia’s use of weapons continues to be directed at innocent civilians, civilian sites and medical facilities, with apparent intent to cause chaos and panic among the population."

    "Thailand desires peace," he added. "But peace must come with safety and security of the people."
