One dead, six missing after tug capsizes off Busan, South Korea

The cook is the only member of the tug's eight-strong crew who is so far known to have survived the incident.

Another crewmember, identified as a 57-year-old Korean national, was found unconscious and was later pronounced deceased after he was brought to hospital.

The remaining crewmembers, which include an Indonesian and five Korean nationals, have not yet been found despite an extensive search operation by the coast guard, the Republic of Korea Navy, the South Korea Ministry of Oceans and Fisheries, and local fire departments.

The Busan Metropolitan City Government has meanwhile extended assistance to the families of the missing Korean crewmembers.
