A fire broke out at a karaoke facility in Busan, killing nine people including three migrant workers from Sri Lanka and injuring 25 others, police said on Sunday.
The blaze started at one of the 28 rooms at the karaoke lounge on the third floor of a six-story building in the southeastern port city around 8:55 p.m. Saturday, according to the witnesses and the police.
All of the victims -- seven men and two women -- died from inhaling toxic gases, police said.
One of the injuries was serious, but the others were non-life threatening, police said.
Police said smoke apparently made customers unable to find exits and led to the large toll.
Police said they are investigating what caused the fire based on witness accounts that a torrent of flames started with a bang sound.
