Among them are Adm Gennadiy Medvedev, chief of the Coast Guard and deputy chief of the FSB's border guard service; Alexey Salyaev, commander of the Don coast guard ship (that rammed a Ukrainian tug); and Andrei Shipykin, commander of the Izumrud coast guard ship (that fired on the Ukrainian vessels).

Also, according to the PGO press secretary, the court issued subpoenas for all the suspects to attend a court hearing on putting them into custody.

In the near future, the notices of suspicion are expected to be served to over 10 servicemen of the Russian Black Sea fleet, the FSB border guard service, the air force and air defense, ranging from junior officers to generals.

As reported earlier, on Nov 25, the Ukrainian Navy's small armoured artillery boats Berdyansk and Nikopol, as well as the Yany Kapu tugboat were sailing from the Black Sea port of Odea to Mariupol on the Sea of Azov. Four Russian coast guard ships intercepted the group near the Kerch Strait. The Russian border ship, Don, rammed the Ukrainian tugboat, damaging it.

The Ukrainian naval group decided to continue their journey since they were acting within the framework of international maritime law. When the boats approached the Kerch Strait, Russia announced that the passage was closed.

The Ukrainian crews then reversed and started moving towards the exit from the strait, but the Russian ships began the pursuit. They opened fire and eventually captured the ships and their crews. On Nov 27-28, a Russia-controlled court in Crimea arrested all the Ukrainian sailors, including the injured ones, for 60 days. They were accused of "illegally crossing the Russian border".

Ukraine informed the United Nations Tribunal for the Law of the Sea on the aggression of the Russian Federation in the Kerch Strait. Also, Ukraine is preparing to file a lawsuit with the International Court of Justice.

The State Duma of the Russian Federation decided to award the border guards who had seized the Ukrainian vessels.
