South Korea's military said on Wednesday it had sent back all seven North Korean sailors who were aboard a ship it seized after the vessel crossed into the South's waters a day before.
The boat was towed to a South Korean border island after crossing the Northern Limit Line (NLL), the de facto sea boundary between the two Koreas, according to Seoul's military officials.
A North Korean patrol vessel that was tracing the seized ship briefly crossed the NLL but turned back shortly after the South's military broadcast warnings and fired a warning shot.
