29 killed as massive fire rips through 8-storey building in South Korea's Jechon

The fire broke at the fitness centre and quickly engulfed the entire eight-storey building, leaving many trapped inside.

SEOUL: In what could be described as one of the country's deadliest fire disasters, at least 29 people were charred to death and nearly 26 were injured in a major fire that broke out at a fitness centre building in the South Korean city of Jechon. 

The fire broke out around 4:00pm local time (0700 GMT) and quickly engulfed the entire eight-storey building, leaving many trapped inside. 

Twenty victims were found at a public sauna and others elsewhere in the building that houses a fitness centre, public bath and restaurants, the National Fire Agency said. 

"The fire produced so much toxic smoke so quickly, leaving many people unable to evacuate," an agency spokesman said.

Many victims appeared to been unaware of the fire raging outside the bathhouse until it became impossible to flee, he added. 

The death toll may rise further as firefighters continue to search the building, the spokesman said. 

Television footage showed the building consumed by orange flames and issuing dark plumes of smoke, as several people stood waiting to be rescued from an outdoor terrace.

Some were seen jumping from the building onto air mattresses laid out on the ground as dozens of fire trucks and more than 100 firefighters rushed to the scene. 

The blaze -- believed to have started in a parking lot on the first floor -- has been mostly put out, the fire agency said.

Jecheon is in central South Korea, about 120 kilometres (75 miles) southeast of the capital Seoul. 

The disaster forced organisers of the 2018 Pyeongchang Winter Olympics to cancel a planned torch relay event at the city on Friday, Yonhap news agency said, citing the organisers. 

"We decided to cancel the event to mourn the victims," an unnamed official at the organising committee was quoted as saying. 

The fire is South Korea`s worst since 2008 when a blaze at a warehouse in the city of Icheon killed 40 workers. 

President Moon Jae-In expressed regret over the accident and urged officials to make "utmost efforts" for rescue and search operations, his office said. 

The worst fire ever to hit modern South Korea was an arson attack on a subway station in the southeastern city of Daegu that left 192 people dead and nearly 150 injured in 2003.
