A fishing boat from Taiwan's Keelung capsized Friday evening in sea off southern Taiwan' s Kenting, with three crewmen still missing after four others, including a Chinese mainlander, were rescued, sources of the island' s military forces said Saturday.

Rescuers are still searching for the missing crewmen, the military sources said.

Helicopters found the mainland crewman, Chen Huaxin, floating in the sea Saturday morning, and immediately sent him to a hospital in Taitung City, the sources said, adding that Chen' s condition was stable without apparent trauma.
