Explosives stuffed inside a bottle damaged a motorcycle parked at a small mosque in Narathiwat’s Rusoh district on Tuesday but caused no injuries.
Police were alerted at about 11am and rushed to scene with bomb squad and forensic officials.
Debris of the home-made bomb, which had been placed inside a bottle, was retrieved. The explosion left a hole one inch deep and four inches wide. A motorcycle with a Yala license plate parked near the scene of attack was damaged by shrapnel.
Initial police investigation showed that two men on a motorcycle entered the mosque and went to wash their faces at a water tap near the mosque building. They reportedly took the opportunity to place the bottle of explosives near the motorcycle. The blast occurred about two minutes after they left the mosque.
Meanwhile rail services to and from Narathiwat's Sungai Kolok station would resume Wednesday and not Tuesday, as earlier planned, said Piraphon Tapvej, director of the southern centre, Railways of Thailand.
The services were suspended on Sunday morning after an explosion hit a compartment of Train 435 on the Yala-Sungai Kolok route.
Police said the explosive was planted close to the railway tracks and insurgents triggered the bombs just as the ill-fated compartment carrying security volunteers passed the spot. The train had slowed because of a slope, enabling the insurgents to easily choose the target.
The blast killed three volunteers and injured scores of people.
The cleanup, repairing of the track and removal of damaged compartments, were initially planned for completion on Tuesday but have been delayed until Wednesday to allow the 14 daily trains to and from Narathiwat's Sungai Kolok station to start running again.
Meanwhile the relevant authorities including police and the army met to review security plans for trains after the fatal train attacks in Narathiwat’s Rangae district.
They agreed that they would adjust the landscapes of the railway where the 14 daily trains to and from Sungai Kolok pass. Some areas of the route are blanketed with thick forests while others are sloped. They said these landscapes allowed insurgents to use them to attack the trains.
The 24-kilometre route passes 14 villages and four Tambons. Four of the villages are considered risky areas.
The meeting agreed patrols along the route that passed the four villages would be increased and that villages should assign members to join the patrol teams.
