Russian opposition activists plan to hold a new protest rally in Moscow on June 12, which is celebrated as a national holiday in the country, Russia Day.

      “The goal of the action is to express support to the Bolotnaya case "prisoners" and voice protest against illegal persecution of political activists,” Ilya Yashin, a member of the opposition's Coordination Council said. The venue of the march will be announced later, he added.

      The Coordination Council said the event will be held to support the Bolotnaya case suspects ahead of the trial.

      Over 650 people were detained at a protest rally on May 6, 2012, after police clashed with protesters. A total of 12 people are currently facing charges ranging from inciting mass unrest to using violent force against law enforcement officials. Opposition activists say all the allegations are politically motivated and illegal.
