One man was killed and 14 others were injured in South Korea's multifamily house fire, Yonhap news agency said Wednesday. 

The fire broke out around midnight in the parking lot on the first floor of the four-story multifamily house in Seoul. 

A man in his 70s and a woman in her 20s were taken to a hospital in cardiac arrest, but the man died. 

Seven people suffered serious injuries, including burns all over the body, while six others sustained minor wounds such as smoke inhalation. 

Fire authorities mobilized 166 firefighters and 41 equipment to extinguish the fire about 45 minutes later. 

The fire authorities believed that the piloti structure of the house, with columns lined up on the first floor around it, spared fire rapidly while causing difficulties in evacuation. 

The police and the fire authorities were investigating the exact cause of the accident.
