The Baku Court for Major Crimes on July 22 found Sergei Dubakov guilty of terrorism, participation in a criminal group, and illegal border crossing. He was sentenced the same day.
Investigators say Dubakov illegally visited Nagorno-Karabakh, where he joined an illegal Armenian armed group, and took part in military exercises in the Kalbacar district.
Dubakov was detained in January after he arrived in Azerbaijan from Turkey. Investigators say he planned “terrorist and sabotage acts” in Azerbaijan.
Dubakov pleaded not guilty.
Armenian officials have not commented on the conviction.
