At least 12 people died and 121 others were injured in an explosion that rocked a fireworks warehouse in southern Thailand, media reports said on Monday.

The incident – in the village of Mu No – reduced the warehouse and surrounding area to rubble, drone footage showed, reports CNN.

According to reports, two of the victims were children.

292 houses were damaged or totally destroyed due to the explosion, reports Bangkok Post.

The cause of the explosion is still not known.

However, initial investigation suggested it was caused due to a welding error.

Police plan to charge the owner of the warehouse with a criminal offense for “causing the explosion and resulting in people’s deaths and injuries and property damage,” Narathiwat Provincial Police Commander Anuruth Imarb was quoted as saying by CNN in a press conference on Sunday.
