Five Thai paramilitary soldiers were killed and six civilians were wounded when armed assailants attacked the Buketa Sami security checkpoint in Narathiwat province, according to Thailand's military. No organization immediately claimed responsibility and authorities had not announced any arrests.
The assault began on Wednesday evening. The military's Internal Security Operations Command Region 4 said approximately 10 attackers, dressed in black and wearing black brimmed hats, approached in a pickup truck and on motorcycles. They opened fire and used pipe bombs against personnel from Task Force Ranger Regiment 45 guarding the checkpoint.
Authorities said the attackers took three AK-47 rifles, three bulletproof vests and several mobile phones before leaving. Security forces later found the pickup abandoned and burned about 21 kilometers, or 13 miles, from the checkpoint. The supplied account did not identify the dead soldiers or injured civilians, describe the civilians' conditions, or establish who planned the operation.
The government condemned the assault as terrorism and said it threatened national security and efforts to restart peace negotiations. The army commemorated the soldiers' service. Those official descriptions reflected the authorities' response, while responsibility for the attack remained unassigned.
The checkpoint raid followed a car bombing a day earlier outside the former Tanyong police station elsewhere in Narathiwat. That explosion injured one police officer and damaged the building. Police were looking for two people seen leaving on a motorcycle. According to Thailand's The Nation, it was the first car bombing recorded in the southern border region during 2026. The evidence did not establish a connection between the two incidents.
Narathiwat, Pattani and Yala are predominantly populated by ethnic Malay Muslims and have been the center of an armed separatist conflict since 2004. More than 7,000 civilians, security personnel and fighters have been killed over the course of that conflict. The Buketa Sami attack was described as one of the deadliest assaults on Thai security forces in recent years.
Formal discussions between the Thai government and the Barisan Revolusi Nasional, the main separatist organization, had been expected to resume in June following an increase in violence. Negotiations had struggled over questions including self-government, security arrangements and political representation.
The latest attack added pressure to that process without clarifying which armed group, if any, directed it. The verified details were the casualties, the weapons and vehicles described by the military, the equipment taken from the post and the discovery of a burned vehicle. Attribution would require further investigative evidence or a credible claim of responsibility.
