Ukraine's SBU Security Service of Ukraine has banned the entry for five years to four citizens of Serbia and one citizen of the Czech Republic for their trip to the annexed Crimea on the third anniversary of the pseudo-referendum.

"The SBU has verified the information about the stay in Crimea of politicians from European and other countries who arrived at the invitation of the occupation authorities to "celebrate" the third anniversary of the pseudo-referendum. It turned out that four citizens of Serbia and one Czech citizen are illegally located in the territory of the Autonomous Republic of Crimea. The SBU made a decision to ban them from entering Ukraine for a period of five years," SBU spokesperson, Olena Hytlianska, wrote on her Facebook page on Monday.

According to her, information about the citizens of Ukraine in this delegation has not been currently confirmed.

Earlier, Secretary of the National Security and Defense Council of Ukraine Oleksandr Turchynov said that the Security Service should analyze information about the stay in Crimea of politicians from European and other countries to impose sanctions against them. According to him, if this information is confirmed, the question of imposing sanctions against them will be considered at the NSDC meeting.
