Russia's Federal Security Service (FSB) announced on Tuesday September 17th, that three Russian coast guards were injured in a clash with North Korean fishing boats in the Sea of Japan, AFP has reported.
The border guards spotted two North Korean boats, one of which carried out an "armed attack" on them. In addition, the vessel involved had more than 45 people on board and led to three coastal guards being injured with "varying degrees of severity", according to FSB.
In response, Russian coast guards detained the boat, as well as another North Korean fishing boat with 21 people on board.
These incidents happen frequently, and the guards detain North Korean fishermen in the Far East, who use rudimentary and illegal wooden boats, and are given prison sentences.
There are also frequent disputes over-fishing rights in the Sea of Japan which is surrounded by Japan, Russia and both North and South Korea.
In July, North Korea released a Russian fishing boat with a crew of 15 Russians and two South Koreans after it was detained for violating entry regulations.
