SEOUL, South Korea. A worker was successfully rescued on Saturday after being trapped for roughly 13 hours in a collapsed subway construction site in Gwangmyeong, near the capital city of Seoul. Rescue operations remain ongoing as authorities search for another individual who is still missing.
According to Im Gwang-sik, an official from the Gwangmyeong City Fire Department, the man was found approximately 30 meters (98 feet) underground, conscious and responsive beneath the rubble. He was immediately transported to a nearby hospital for medical treatment.
The incident prompted city officials to suspend construction activities and close nearby roads after reports surfaced that a ventilation shaft at the site was in danger of collapsing.
Emergency teams, including dozens of rescue workers, were quickly deployed to the area. Authorities are using heavy equipment, including three cranes, to aid in the search for the second worker, who has yet to be located.
As of reporting time, officials have not released the identities of the workers involved. The cause of the collapse remains under investigation.
Gwangmyeong city officials continue to monitor the stability of the site to ensure the safety of both rescuers and the surrounding area.
