Most fires were extinguished quickly before they could spread to other buildings, except for the fire at Bangchak gas station in Pattani, which took firefighters about two hours to control after the blaze engulfed gas pumps, a fuel truck and a trailer truck parked nearby.
Witnesses reportedly said a group people wearing hijabs rode motorcycles into the gas station at night and ordered all workers to leave the site, threatening that they have bombs. The riders then moved a fuel truck close to the gas pumps before spraying the vehicle with gasoline. Shortly after, an explosion was heard and flames spread through the refuelling area.
On Wednesday Yala and Pattani shut down all 7-Eleven convenience stores until further notice.
