Grigory Skvortsov, who denies wrongdoing in sharing details of the bunkers, will serve his sentence in a maximum-security prison.
A Russian court has found a photographer guilty of treason and jailed him for 16 years for allegedly sharing information about Soviet-era underground bunkers with an American journalist.
The court in the western city of Perm sentenced Grigory Skvortsov on Thursday after a closed-door trial, without giving more details on the charges. Skvortsov, who was arrested by Russian authorities in 2023, has denied any wrongdoing.
The court said Skvortsov would serve his sentence in a maximum-security corrective prison camp.
It also published a photograph of him in a glass courtroom cage dressed in black as he listened to the verdict being read out.
