The attack occurred at about 7pm when a group of soldiers from the 49th Ranger Regiment were heading back to their base in a pickup truck. They had been to a sporting event at an Islamic religious school in the area and were driving along a road that went past Moo 5 village of tambon Kalong.
Police said an unknown number of armed militants hiding on both sides of the road, which runs through a dense rubber plantation, opened fire at the pickup and a 5-minute gunfight ensued. The insurgents fled when reinforcements arrived.
Seven soldiers were injured in the ambush and were sent to Si Sakhon and Rue So hospitals, where two paramilitary rangers — Nattapong Pimrat and Wissanu Nuankaew — later succumbed to their wounds.
