Greenpeace activists read the names of the Arctic 30 and hold a banner reading: 'Lasst Unsere Aktivisten Frei' (Free Our Activists) during their protest at the Russian Consulate in Frankfurt, Germany. They support the 28 Greenpeace International activists, as well as a freelance photographer and videographer who are currently held in custody following a peaceful protest on September 18, 2013 against risky oil drilling in the Arctic by Gazprom.
