Seoul: Fire officials in the South Korean capital say a large blaze at a construction site near a 600-year-old palace has killed at least four workers and injured about 20.
They say Gyeongbok palace wasn`t damaged by today`s fire, which filled Seoul`s central district with smoke.
Seoul Metropolitan Fire and Disaster official Kim Byung-ro says the workers died after inhaling toxic smoke. One of the injured is in critical condition.
Kim says the blaze started when a spark from construction at the site of a national art museum landed in combustible material.
About 170 firefighters extinguished the fire in about an hour.
In 2008, an arsonist destroyed a gate in Seoul regarded as a South Korean national treasure. It`s now being rebuilt.
