SEOUL, Dec 11 (Reuters) - One worker died and two were missing and feared buried at a library construction site in the South Korean city of Gwangju on Thursday, after an iron structure at the site collapsed, fire authorities said.
A fourth person was trapped and authorities were trying to free the worker, the Gwangju fire agency said.
The collapse occurred while concrete was being poured at the construction site, authorities told reporters at a briefing.
