BANGKOK: The death toll from a huge fire in a Bangkok music bar has increased to 30, officials said Tuesday.

More than 70 people were injured, with 24 of them still in critical condition, according to a statement by the Bangkok Metropolitan Administration.

The blaze at the Rong Beer Na Ladprao bar was the city’s deadliest in 17 years. It broke out late Sunday in a northern part of the Thai capital, and firefighters needed half an hour to bring it under control. The fire left 25 people hospitalized in critical condition, city officials said.

Bangkok Gov. Chadchart Sittipunt said most of the deaths were caused by smoke inhalation.

By daybreak Monday, the site had been cordoned off as dozens of forensic officers sought clues about what caused the fire. The bar’s street-facing windows were blown out, and debris littered the sidewalk, including charred television sets, speakers and an electric guitar. Associated Press journalists looking through the shattered windows could see empty beer bottles still sitting atop burned tables.
