Three ships from the Ukrainian Navy, in violation of Articles 19 and 21 of the UN Convention on the Law of the Sea, crossed the Russian maritime border on 25 November, entered the temporarily closed area of the country's territorial waters, and were moving from the Black Sea toward the Kerch Strait, according to the Russian Federal Security Service (FSB).
The incident has been captured on video.
The Ukrainian ships did not react to legal demands of the ships accompanying them and made dangerous manoeuvres, the FSB noted. Another group of ships was heading for the Kerch Strait from the port of Berdyansk on the Sea of Azov.
