That is one reason why it is launching new provocations against Russia. Yesterday Ukrainian forces reportedly occupied a town within the neutral zone between the government controlled part and the rebel held Donetsk area. Today the Ukrainian navy sent a tug and two small gun boats, recently acquired from the U.S. Coast Guard, Ukrainian build Gurza-M class types, to pass through the Kerch Strait into the Sea of Azov.

When the ships entered Russian waters without announcing their intent, a Russian coast guard ship rammed (vid) and damaged the tug. The two gun boats escaped but did not pass the strait. The pictures show the melee at sea.
