On Wednesday, Odesa was marking the fourth anniversary of street clashes and a massive fire in the House of Trade Unions, which on May 2, 2014, killed 48 people.

The State Border Guard Service of Ukraine on May 1 banned entry into the country of three "hostile" individuals -- citizens of Italy, the Czech Republic and Russian Federation, who came to Ukraine to "cover" the 4th anniversary of the May 2 tragedy in Odesa.

The citizens of Italy and the Czech Republic were denied crossing into Ukraine in the Boryspil International Airport based on information received from other security agencies. As reported, they have been falsely covering the events in Ukraine over the recent years, the Border Guard Service reported.

"In particular, an Italian citizen under the guise of a photographer stayed in the occupied Donbas and repeatedly appeared on the so-called "Oplot TV Channel" where he voiced frankly falsified information about developments in eastern Ukraine. A citizen of the Czech Republic, who was also banned from entering Ukraine, turned out to be a journalist of a political publication. He distorted information and falsely covered the Ukrainian events as well. Of course, no one should hope for impartiality of those 'journalists' in covering the May 2 events in Odesa," the report said.
