MOSCOW, November 26. /TASS/. All three vessels of the Ukrainian Navy, which violated the Russian state border, have been detained in the Black Sea, weapons were used to force them to stop, the Public Relations Center of the Russian Federal Security Service (FSB) reported.

"The Ukrainian Navy’s vessels the Berdyansk, the Nikopol and the Yany Kapu, which violated Russia’s state border this morning, made another attempt of committing illegal activities in Russia’s territorial sea at 19:00 Moscow time on November 25," the FSB said. "They did not respond to legitimate demands by the ships and boats of Russia’s FSB Border Guard Service escorting them to stop immediately and performed dangerous maneuvers."

According to the FSB, "weapons were used to force the Ukrainian warships to stop." As a result, all three vessels of the Ukrainian Navy were detained in Russia’s territorial waters in the Black Sea. "Three wounded military servicemen of the Ukrainian armed forces received medical assistance," the FSB said, adding that there was no threat to their lives.

A criminal case has been initiated over violation of Russia’s state border.

The FSB stressed that Ukraine was aware of the procedure for warships’ passage through Russia’s territorial sea and Kerch-Yenikale Canal. "They have already used that procedure for innocent passage," it said.

The FSB’s border directorate for Crimea earlier reported that three Ukrainian warships had illegally crossed Russia’s state border in the Black Sea and entered Russia’s territorial waters performing dangerous maneuvers. Later on, the FSB said that two more Ukrainian warships had sailed off from Berdyansk to join the three vessels. However, they later turned back.

The FSB stressed that "before making such dangerous and irresponsible decisions, the Kiev leadership should have thought about possible consequences of its actions."

Russia’s Federal Security Service said it had irrefutable evidence of Kiev’s using the Ukrainian Navy to stage a provocation in the Black Sea and promised it would be made public soon.

Three Ukrainian Navy vessels, which violated Russia’s state border and were detained in the Black Sea are being delivered to the port of Kerch (a city in eastern Crimea), Anton Lozovoy, an officer of the Russian Federal Security Service (FSB) State Border Directorate for Crimea, said in a video commentary on Monday.

"All three vessels have been detained and are being delivered to the port of Kerch," he said.

According to Lozovoy, three Ukrainian military servicemen who sustained minor wounds have received medical care.
