Putin does not exclude to finish work started by Tsar Nicholas II and return Istanbul to Christians, Marcel H. Van Herpen, a security expert specializing in Russia, Eastern Europe, and the post-Soviet states, wrote on Twitter citing Basta News Agency.

"If Turkey does not cease supporting the Syrian branch of Al-Qaeda, I seriously intend to complete the work started by the last Tsar Nicholas II. During World War I, he (the Tsar) tried to return Constantinople (Istanbul) to Christians and secure Russia’s access to the sea by way of the Bosporus and Dardanelles Straits, but bad luck prevented him," Putin told the delegation of the Ukrainian Orthodox Church.

The Head of Russian State went on saying Russia will support the sovereignty of Greece over Cyprus and called on the Turkish regime to end its ten-year occupation of the Mediterranean island.
