A family of three fell into the sea near the Mysterious Sea Road in Uisin-myeon, Jindo-gun, South Jeolla Province, on Saturday.
According to Yonhap, the incident occurred at around 1:51 p.m. Saturday near the Mysterious Sea Road. A 3-year-old boy and his mother were transported to a hospital in cardiac arrest.
