Insurgents detonated a homemade bomb hidden in a pick-up truck to ambush patrol police in Narathiwat's Sungai Kolok district Friday morning, injuring eight civilians nearby.
Sungai Kolok district police chief Pol Col Maitree Chimcherd said the explosion occurred at 6.15am in front of an electrical appliance shop in downtown Sungai Kolok.
The explosion caused fire to breakout in the four-storey shop houses. Ten fire engines took more than three hours to put out the fire.
During the blaze, the owner of the Pro-Computer and OA Thailand, which sells mobile phones and all kinds of electric appliances, and three family members fled to the rooftop.
Firefighters used a crane to rescue them from the rooftop.
Police found a wrecked Isuzu pick-up truck with fake license plates at the scene. Police believe insurgents hid a 50-kg bomb stuffed inside a cooking gas cylinder in the truck. The blast also damaged three vehicles belonging to the shop and another motorcycle.
The eight injured people were passers-by who were returning from a fresh market nearby. They were rushed to the district hospital.
Police said insurgents detonated the bomb with a walkie-talkie after they saw a patrol car of policemen from Sungai Kolok police station driving past the scene. However, the blast did not affect the police car.
