"We're working to correct the wrong designation of the temporarily occupied city of Sevastopol by the Guinness Book of World Records. Crimea is Ukraine. Records must be honest," she wrote on Twitter on December 3.

As was earlier reported, Belarusian national Alexander Bendikov, who set a world record for the most nails balanced on the head of a single nail in Russian-annexed Crimea's Sevastopol, received his Guinness World Records certificate where the city was indicated as the one located in the Russian Federation.

He balanced 349 nails on the head of a single nail.
