The Indonesian navy on Sunday sank two Thai vessels after a court confirmed last Tuesday that the ships were involved in illegal fishing in the waters of Anambas, one of the Riau Islands.
The vessels were destroyed in Anambas waters, near the South China Sea, and took only around five minutes to sink.
MV Kour Son 77 was caught by the navy on November 14 with six crew on board - two from Thailand, three from Myanmar and one from Laos. Another vessel, KM G Chawat 5, was seized by the navy on December 11, after it could not provide any legal documents to operate in Indonesian waters.
Navy Western Fleet commander Rear Admiral Widodo said the sinking was in line with Indonesian law, which had been confirmed by a court verdict.
"With the quick verdict, we hope that it will deter foreign poachers from entering our territory," he said.
