Two Vietnamese nationals are among the four sailors missing in a South Korean fishing boat fire accident on Tuesday morning that killed two other crew members.
The Vietnamese sailors are identified as Nguyen Van Chuc, 37, and Vo Van Huu, 22.
The Munseong 103 caught fire in waters about five nautical miles northeast of South Korea’s islets of Dokdo, called Takeshima in Japan, at about 5 a.m. local time, Yonhap News Agency quoted South Korean authorities as saying.
Aboard the 29-ton vessel were eight South Koreans and two Vietnamese.
Six were rescued from the ship, but two of them died later. Two South Koreans and two Vietnamese went missing.
The Vietnamese embassy in South Korea said it is keeping close contact with local authorities for latest update of the rescue.
Search operations are still under way.
The blaze is estimated to have started from the engine room, but the exact cause is still under investigation.
