At least 13 people were killed and 41 others injured after a fire swept through a nightclub in Chonburi province in south-eastern Thailand.
The fire broke out at 01:00 local time on Friday (18:00 GMT Thursday) at the Mountain B nightspot in Sattahip district, police said.
Footage circulating online shows people fleeing the club screaming, some with their clothes alight.
Rescuers say flammable material on the walls may have exacerbated the blaze.
The venue in Chonburi, a province located 150km (90 miles) south of Bangkok, was a single-storey complex measuring 4,800 square metres (51,660 square feet).
Firefighters battled for more than two hours to bring the fire under control, local media reported.
So far, all those who died are believed to be Thai nationals.
The exact cause of the fire has yet to be determined, though officials from the Sawang Rojanathammasathan Rescue Foundation said flammable acoustic foam on the club’s walls might have accelerated the speed at which the fire tore through the venue.
Thai Prime Minister Prayuth Chan-ocha said on Friday that families of the victims would receive aid from authorities and urged entertainment venues nationwide to ensure they had proper emergency exits and safety measures in place.
This is not the first time a deadly fire has broken out in a Thai nightclub.
In 2009, more than 60 people died in Bangkok after a fire spread at the Santika Club in the early hours of New Year’s Day. Two men, including the owner of the club, were jailed in 2011.
