Two biomass power plants in the southernmost province of Pattani were set on fire early this morning.
The arson attacks occurred simultaneously in Mae Larn and Sabayoi districts.
In Mae Larn, three armed individuals, dressed in black, invaded the biomass plant in Moo 7 shortly after midnight.
They forced security guards from the premises before a second group entered the buildings, poured petrol onto the machinery and items stored inside and set them ablaze. A car parked outside the building was also burnt.
The fire damaged buildings and property, but no one was injured.
A similar attack took place at a biomass power plant in Sabayoi district. Police were alerted to the blaze at about 1am.
An initial examination of CCTV footage revealed that four armed individuals, again dressed in black, deliberately set fire to the building.
