A fierce fire raged through a paper recycling factory in Muang district of Samut Sakhon on late Saturday morning.
The fire broke out at the factory in tambon Ban Koh at about 11am, said police.
The provincial disaster prevention office, Bang Pla tambon administration organisation and local authorities nearby deployed fire trucks to the site. Large bundles of compressed paper for recycling were engulfed in flames that spread quickly, said police.
The fire has so far destroyed about one-third of the 30-rai site.
As of 12.30pm, the fire had not been brought under control. Some firefighters had to be withdrawn from the area as the fire-gutted building structure collapsed, according to the Fire & Rescue Thailand Facebook page.
Police are investigating the cause of the blaze. Damage could not be estimated.
