The death toll from a collision between Japanese and South Korean freighters earlier this week rose to six Saturday with the discovery of three bodies in the South Korean vessel.

Two sailors from the 2,747-ton South Korean freighter Sun Trust remain missing. The ship collided Thursday night off Shizuoka Prefecture with the 462-ton sand transporter Koyo Maru No. 2.

None of the Koyo Maru's crew of three was hurt. The Sun Trust's crew consisted of seven Koreans and six Myanmar nationals. Two of the Koreans were found in the sunken freighter Friday. The ship's captain, Jeong Dae Hyun, 59, was rescued following the 9:55 p.m. crash but died soon after.

Five sailors from the Sun Trust were rescued. The collision occurred about 5.5 km southeast of the Omaezaki coast, according to Japan Coast Guard officials.

The Koyo Maru, owned by Shizuoka-based shipping firm Koyo Kaiun, was heading to Kimitsu, Chiba Prefecture, from Aichi Prefecture. The Sun Trust was en route from Shizuoka to Pusan, South Korea, with a cargo of plaster stone.
