Barnaul

Lilia Chanysheva, who headed Navalny’s headquarters in the central Russian city of Ufa, was sentenced to 7½ years in prison on similar charges in June, and Vadim Ostanin, who previously headed Navalny’s office in the southern Siberian city of Barnaul, was handed a 9-year sentence in July on charges of organizing an extremist community.

Vadim Ostanin, who had run Navalny's local headquarters in the Siberian city of Barnaul, had carried out only "legal political work", Navalny's team wrote on the Telegram app.

Ostanin was arrested in December 2021 and held in Moscow before being transferred to Barnaul, where he stood trial.

"Upon my arrival in Barnaul from Moscow, without explanation, I was placed in a solitary cell, about six square metres, in a basement with a window covered with debris," Ostanin wrote in a letter published by Navalny's team.

Barnaul products have been common on American shelves in recent years, including ammunition for military-style rifles, hunting rifles and American handguns.
