Deadly clashes have broken out again along the disputed Thailand-Cambodia border. Seven civilians were killed and 20 wounded in Cambodia, while three Thai soldiers died in the fiercest fighting since a 5-day battle in July. Both countries blame each other for violating a US-backed ceasefire deal signed just six weeks ago. Cambodia’s senate president, Hun Sen, said Cambodia retaliated after waiting for more than 24 hours to respect the ceasefire and evacuate civilians. "Cambodia needs peace but Cambodia is compelled to counterattack to defend our territory," he said on Facebook. Hun Sen said Cambodia has strong bunkers and weapons giving it an advantage. Thailand’s defence ministry said it is “determined to defend its sovereignty and territorial integrity” and will act as needed. Thai prime minister Anutin Charnvirakul said, “There will be no talks. If the fighting is to end, [Cambodia] must do what Thailand has set.” The conflict spread on Tuesday with the Thai navy moving to push Cambodian forces from Thai territory in Trat province. Thailand accused Cambodia of using rocket launchers, bomb-dropping drones, and artillery. Artillery shells hit two civilian homes in Sa Kaeo province but caused no injuries. Cambodia accused Thailand of firing into civilian areas, destroying temples, cultural sites, and public services. Over 125,000 people in Thailand and 21,000 in Cambodia have evacuated border areas. This long-standing border dispute began over a century ago and flared violently in July killing 48 and displacing 300,000. Despite a ceasefire brokered by the US, both sides repeatedly accuse each other of violations including landmine laying and firing on civilians.
