Tokyo: Japanese authorities said they rescued "dozens" of North Korean fishermen after their boat collided with a Japanese patrol vessel and sank Monday in areas crowded with poachers.
Coast Guard officials earlier said that about 20 North Korean crewmembers were thrown into the sea after their steel boat collided with a Japanese Fisheries Agency inspection boat off Japan's northern coast.
Officials later said they rescued far more than first thought, but did not give an exact number. They said they were still doing the math and making sure nobody was missing.
The North Korean boat sank about half an hour after the collision in the area called Yamatotai, known as rich ground for squid fishing northwest of the Noto Peninsula.
The North Korean boat had made an unauthorized entry into the Japan's exclusive economic zone and the collision occurred just as the Japanese patrol boat was warning it to move out, Fisheries Agency official Satoshi Kuwahara told reporters. He said officials were investigating if the North Korean ship was actually carrying out illegal fishing, and how the two ships collided.
The Coast Guard office in Niigata said officials handed the North Korean fishermen to other boats in the area after notifying Pyongyang's rescue coordination center to arrange their way home. It said the North Korean crewmembers had no life-threatening conditions.
Fisheries Agency officials said the Japanese patrol ship had no major damage and was able to move on its own.
The collision site near Yamatotai is disputed between Japan and North Korea, which have no diplomatic ties.
The two countries also have disputes over Japan's 1910-1945 colonial rule of the Korean Peninsula, as well as North Korea's nuclear and missile development and the issue of the North's abduction of Japanese citizens in the 1970s and 1980s.
Japan has stepped up patrols in the area in recent years as North Korean squid poaching has surged. This year, ships from Japan's Fisheries Agency and coast guard have been patrolling in the area since May, Kuwahara said.
Japanese fisheries patrollers have issued nearly 500 expulsion orders to poachers between May and August this year, most of them from North Korea, according to the Fisheries Agency.
Experts say the increase in North Korean squid poaching is due to the country's campaign to boost fish harvests. The poachers are believed to be related to an influx of ghost boats that have washed onto Japan's northern coast, fisheries officials have said.
In June, Japan's coast guard pushed more than 300 North Korean boats back from the same waters where Monday's incident occurred. Japan also said an armed North Korean fishing boat aimed a gun at and "threatened" a Japanese patrol ship in August.
