Gwangju: President Lee Jae Myung ordered authorities Thursday to make all-out efforts to rescue workers trapped in the rubble of a collapsed library construction site in the southwestern city of Gwangju. Lee gave the instruction during a policy briefing by the labor ministry in the administrative city of Sejong, after a steel structure at the construction site collapsed at around 2 p.m., killing one worker and trapping three others. Lee called on the relevant ministries to "mobilize all available personnel and equipment" to rescue the trapped workers.

According to Yonhap News Agency, authorities have located one of the trapped workers and launched an operation to rescue him, while two others remained unaccounted for.
