Four workers were killed in an explosion at a shipyard in the southeastern city of Changwon on Sunday, the national fire agency said.
The workers were inside the oil tanker when the accident took place.
Rescuers search for victims after an explosion at an STX Offshore and Shipbuilding plant in Changwon, South Korea, yesterday.
Rescue officials recovered the bodies of the deceased and are working on identifying them, authorities said in the afternoon. Explosion occurred at 1140 Seoul time Aug 20, most probably caused by a spark or open light in a compartment, full of explosive paint fumes. The shipmaker clinched an order of four long-range crude oil and product tankers from the Greek shipping firm in 2015.
