A regional court in the southwestern city of Saratov jailed the six men for up to three and a half years, court spokeswoman Olga Pirueva confirmed on Friday.
“Yes they were convicted,” the spokeswoman, Olga Pirueva, said.
According to the court ruling, the men were found guilty of continually practicing the activities of an “extremist organization” following a 2017 ruling from Russia’s Supreme Court that classified it as such and ordered it to disband.
In February, Danish construction Dennis Christensen was found guilty by a Russian court of organizing “extremist” activities because of his association with the group, and jailed for six years.
Russia’s persecution of Jehovah’s Witnesses has long been criticized by human rights organizations, with the group Human Rights Watch also pointing to the “dozens of home searches, raids, interrogations, and other acts of harassment and persecution.”
