Russian-Armenian reporter Aram Gabrelyanov has been banned from entering Armenia, Sputnik Armenia reported on Tuesday, citing anonymous sources and Viktor Soghomonyan, a professor at the Moscow State Institute of International Relations.

Gabrelyanov, the founder of the News Media holding, was expected to deliver a lecture as part of a training for journalists organized by Soghomonyan.

“Upon his arrival in Yerevan, he was asked to wait, then he was told there were problems with his passport. As a result, it turned out that he was on the list of undesirable persons,” the source said.

Aram Gabrelyanov, who is a vocal critic of the Armenian government, had to take the first flight back to Moscow.

He has not yet commended on the incident.
