The journalists have recorded three such cases in total.
During four months of watching Medvedchuk, all other private planes traveled to Moscow and other Russian cities landing in Gomel (Belarus).
Infrastructure Minister Volodymyr Omelian confirmed that the ban on direct flights between Ukraine and Russia extends to private aircraft. He said such flights have to be sanctioned by the Ukrainian and Russian authorities.
Medvedchuk's Ukrainian Choice NGO told journalists the permission for direct flights is issued by the Ukrainian and Russian authorities, citing participation in official talks as a key reason.
"Viktor Medvedchuk's visits to the Russian Federation are official and connected with his diplomatic activity. During these visits, he takes part in negotiations with the leadership of the Russian Federation. As a result of such negotiations Nadiia Savchenko, Yurii Soloshenko and Hennadii Afanasiev were released. Negotiations to free Oleh Sentsov, Oleksandr Kolchenko, Mykola Karpiuk and Stanislav Klykh are currently underway," the NGO explained.
