Earlier, during a PACE session, Bulgarian President Rosen Plevneliev claimed that Crimea is part of Ukraine, and Ukraine itself is a part of Europe.
"The Bulgarian president says that Ukraine is a part of Europe. I hope he didn’t forget that Russia is a part of Europe too," di Borgo retorted via Twitter.
Le Président bulgare indique que l'Ukraine c'est l'Europe Oui si il n'oubliait pas que la Russie c'est aussi l'Europe #ConseilEurope— Yves Pozzo di Borgo (@YvesPDB) 26 января 2016
Crimea rejoined Russia in March 2014, after more than 96 percent of voters in a referendum held among the local electorate were cast in favor of seceding from Ukraine and joining Russia.
