There was a territorial dispute over the ownership of the Tuzla Island between Ukraine and Russia in October 2003. The Russian authorities claimed the 1954 transfer of Crimea to Ukraine had only included the continental parts of Crimea, even though the Tuzla Island had been administratively part of Crimea since 1941. Since the 2014 Russian annexation of Crimea Tuzla island is a de facto part of Russia and forms a foundation for the Crimean Bridge.
