BANGKOK, Feb. 13 (UPI) -- A bomb in a parked pickup truck exploded in Thailand Sunday, injuring 18 people and setting 12 wooden buildings on fire, police said.
The blast was set off by remote control around 9:50 a.m. in Yala, the Bernama news agency reported.
Police said security camera video showed a man parking the truck in front of a row of shops around 7:30 a.m.
The explosion was apparently planned to target a passing military convoy, the report said. Three of the injured were soldiers.
Officials said 11 of the 18 injured were treated and released and the others remained hospitalized, the Bangkok Post reported.
The ensuing fire burned out 12 wooden shop-apartment buildings, and took 3 hours to extinguish, Bernama said.
Police said they suspect the bombing was the work of Muslim separatists, the Post reported.
