Fire tore through a refrigeration warehouse under construction in an industrial district south of Seoul on Monday, killing 40 workers and sending toxic fumes into the air, officials said... An official at Korea 2000, a logistics company that owns the facility, said the building was under construction and was intended for refrigeration purposes. The official said workers were applying the final touches when the fire broke out. The official requested anonymity, saying company rules prohibit employees from speaking to the media.
