Kerch Strait incident

On November 25, 2018, three Ukrainian naval ships illegally crossed Russia’s border and tried to carry out some illegal activities in Russian territorial waters. They ignored legitimate demands for coming to a halt from vessels belonging to the FSB Border Service and the Black Sea Fleet, and continued maneuvering dangerously. In order to stop the Ukrainian ships, weapons had to be used. The three vessels were detained in Russian territorial waters.

Criminal investigation was launched into the border incident. The Ukrainian ships’ crew were arrested. They are charged with violating the Russian border under Article 322.3 of the Russian Criminal Code and, if found guilty, may face up to six years in prison.
