The cause of the fire is still unknown and all victims so far have been identified as Thai nationals, police said. A separate statement from the Chonburi emergency service described 14 of the injuries as serious. The fire at the Mountain B nightclub, about 111 miles southeast of the capital Bangkok, started at about 1:00 a.m. local time, Wuttipong Somjai, head of a local police station, told Reuters by phone.

Sawang Rojanathammasathan Rescue Local television footage showed people fleeing the blaze and emergency workers dousing the flames and peering through the burned facility, with shoes and bottles strewn on the ground. A witness named Nana told local television that she was with five friends when the fire broke out at the site. “I saw flames above the stage, on the right side. I think it was around the same time that the singer on stage saw it and yelled “fire!” and threw the microphone at him,” he told television network PPTV. “I saw many of the pub boats covered with fire inside.” The fire has killed at least 13, according to Thai officials. Sawang Rojanathammasathan Rescue The incident comes 13 years after pyrotechnicians set fire to a New Year’s Eve party at the packed Santika nightclub in Bangkok, killing 66 people. Investigations into the fire found several key breaches at the club, official corruption and revealed lax safety practices in entertainment venues at the time. Prime Minister Prayuth Chan-ocha on Friday assured the families of the victims that they would receive help from the authorities and urged entertainment venues across the country to ensure they have adequate emergency exits and security measures.
