The attack took place at 2.30pm when a roadside bomb placed under a power pole exploded on Ban Ri Ngae Road in Tambon Phadungmat as rangers drove by in a pickup truck.
The explosion sent the truck into a roadside ditch and the suspected insurgents opened fire at the rangers with assault rifles from a wooded area. Five rangers were killed before the assailants fled.
The attackers also sprinkled the road with spikes to hinder officers’ pursuit.
