Eight people are injured after a fire and suspected explosion occur in an apartment facilities and management office in Gyeongsan, in southeastern South Korea, police and city officials say. The incident starts at 8:29 a.m. when a fire breaks out inside the office where management staff are gathered, according to officials. One report describes the event as a suspected explosion and another as suspected arson involving a resident. Firefighters extinguish the blaze about 20 minutes later. Among the injured, one person is reported in critical condition. Several elderly people are also among those hurt, with at least five elderly residents inside a senior center next to the office at the time of the incident. People reportedly gathered at the office to discuss apartment management regulations. Police say they plan to determine the exact cause after the fire is controlled, including by investigating what triggered the fire and interviewing people at the scene. A person believed to be responsible is taken to a hospital, and police reportedly believe he entered the office with flammable material shortly before setting it on fire.
