At least ten people have been killed, including three children, in a blast at a fireworks warehouse in a market in southern Thailand on Saturday.

The explosion in Sungai Kolok, on the Malaysian border, seriously injured at least 115 people and is thought to have been caused by construction work.

Residents described hearing a huge explosion at around 15:00 (09:00 BST).

The force shook buildings, shattered windows and collapsed roofs, sending a massive plume of smoke into the air.

The explosion has also destroyed a large part of the town in Narathiwat province.

The market fire has been brought under control and a preliminary investigation indicates a "technical error" in steel welding during construction work on the building was responsible, local governor Sanon Pongaksorn said.

At a press conference on Sunday, he said the death toll stood at 10, but that it may rise because rescuers had found parts of two bodies that they could not identify.
