The attack in Pattani province was believed to have been carried out by Muslim insurgents who targeted the outpost used by special forces, said police Col. Keerati Waeyoosoh, the Pattani police superintendent.
Keerati said the bomb, made from a cylinder gas tank, was placed inside a car that had been stolen earlier Saturday from a tire shop whose owner was shot three times but survived. The car was then parked before it exploded outside a roadside restaurant adjacent to the police camp, which was destroyed by the blast.
The insurgents are known for drive-by shootings and bombs placed on parked motorcycles and cars.
