YEONGDEOK, South Korea, Sept. 10 (Yonhap) -- Three migrant workers were found dead, and another one is in a coma, following an accident inside an underground tank at a fishery products processing factory in the eastern county of Yeongdeok on Tuesday, local fire authorities said.
The four -- three Thais and one Vietnamese -- were found at the bottom of the tank at 2:30 p.m., according to the North Gyeongsang Province Fire Service Headquarters.
The workers, whose names have yet to be made public, are believed to have suffocated while doing maintenance work inside the tank at the factory in Chuksan Port in Yeongdeok.
The 42-year-old and 28-year-old Thai workers and the 53-year-old Vietnamese person died in the accident, and the other victim, a 34-year-old Thai, is currently in a coma, the fire headquarters said.
The tank stores byproducts from the processing of fish and shellfish, it added.
