>Russian men subject to mobilization are now not allowed out of Belarus. More than 10 people have been taken off flights today.
>Gleb, 23, from St. Petersburg tried to leave Russia for the third time. At first, he was not allowed to cross the border at Domodedovo Airport when he tried to fly to Dubai. Then they took him off the bus that was going to Belarus - the border guards told Gleb that he was on the lists and could not leave the country.
>Today, the guy managed to leave Russia - through roundabout paths he got to the territory of Belarus and reached Minsk, from where he had a scheduled flight to Turkey. However, he was not allowed on the plane: the border guard officer referred to paragraph 4 of Article 6 of the Agreement between the Republic of Belarus and the Russian Federation on ensuring the rights of citizens to freedom of movement and forbade him to leave.
>According to one of the airport employees, the restrictions came into effect on October 20, and before that, allegedly, all men were released without problems. According to Baza, 11 men were taken off flights from Minsk today alone.
