Russian vessels and combat aircraft went for provocations in the waters of the Sea of Azov. The press office of the Ukrainian Navy's HQ posted this on Facebook.
The Ukrainian crews reported two incidents on September 20 and 21. A scout ship of the Russian Navy approached the Ukrainian vessels at the distance of two cable lengths, which is a rude violation of the international maritime regulations. On another occasion, Sukhoi Su-27 fighter approached Ukraine's transport aircraft Antonov An-26.
The Ukrainian forces located near Kerch Strait remain on high alert, the Navy HQ said. Specifically, armored cannon boats Lubny and Kremenchuk protect the two Ukrainian vessels; combat aviation is ready for deployment, too.
On September 23, Donbas and Korets, the vessels of the Ukrainian Navy entered the Kerch Strait, currently controlled by the Russian troops. The Ukrainian crews did not ask for any permission from the Russian side, which is in line with the Ukrainian and the international law; it considers Crimea a part of Ukraine's territory.
The Ukrainian side noted that the vessels should be included in the compound supposed to be deployed in the new naval base of the Ukrainian Navy, established in Berdyansk. Strengthening the groupings of the Ukrainian Navy in the Sea of Azov is a response to Russia's aggressive actions in the Sea of Azov.
According to the agreement of 2003, the Sea of Azov is an internal sea of two states where civil and military vessels under the flags of Ukraine and the Russian Federation can freely enter through the strait and go to their ports.
