Two territorial defence volunteers were killed and 16 injured when a roadside bomb, reportedly built inside a 50-kg gas cylinder, hit their truck in Sukhirin district, Narathiwat, on Friday. Police say insurgents likely carried it out in retaliation for a 9 September security operation. For Thai SMEs in the far south, expect road checkpoints, security movements and possible delays on local routes. Businesses elsewhere have no direct action to take.
