Narathiwat is one of three Muslim-majority provinces in mostly Buddhist Thailand where a separatist insurgency has claimed more than 4,300 lives since 2004.
A roadside bomb has exploded in a southern Thai village where three people were fatally shot the night before by suspected Muslim insurgents.
Police Capt. Pairat Kiatcharoensiri said the bomb went off on Wednesday morning in a remote village of Narathiwat province when a truck carrying police arrived. None were wounded.
He said a man and two women were shot there on Tuesday evening by about a dozen armed men. Police suspect the gunmen were Muslim insurgents who believed their victims were informants. The killings could also have been staged to lure security personnel to the scene to be attacked.
