Ukraine has appealed to the leadership of the United Nations in relation to the holding by the Russian Federation of presidential elections in the temporarily occupied Crimea.

"Ambassador Yelchenko in a letter to the UN Secretary-General, President of the Security Council and UN membership: Russian presidential elections in the occupied Crimea violate the UN Charter. The outcome of such illegal elections will be null and void," Ukraine's Permanent Mission to the UN wrote on Twitter.

Yelchenko enclosed with the letter a Resolution of the Verkhovna Rada of Ukraine on its Address to the international community in regard of organization of illegal elections of the President of the Russian Federation at the temporarily occupied territories of Ukraine – the Autonomous Republic of Crimea and the city of Sevastopol.

As UNIAN reported earlier, Russia scheduled their presidential elections on March 18, the anniversary of the illegal signing of Crimea and Sevastopol's accession to Russia.

Earlier, Ukrainian President Petro Poroshenko said Ukraine would work toward having an international community not recognize the "elections" in Crimea and introduce sanctions against their organizers.

Estonia and Canada have already stated their non-recognition of Russian elections in Crimea ahead of their holding.
