SEOUL, Nov. 20 (Xinhua) -- South Korean officials on Thursday visited a wartime undersea coal mine in Japan, where the remains of Korean forced laborers were recently discovered, according to the Ministry of Interior and Safety.

The Chosei coal mine, an undersea mine in Yamaguchi prefecture, experienced a flooding in 1942 that claimed the lives of 183 people. The victims included 136 Koreans who had been forcibly mobilized.

Human bone fragments, including a skull, were discovered during an underwater recovery operation in August this year.

The ministry planned to inspect the coal mine through the visit and explore ways to support the excavation of the remains. Enditem
