Greenpeace activists read the names of the Arctic 30 and hold banners reading: 'Lasst Unsere Aktivisten Frei' (Free Our Activists) and 'Schützt die Arktis' (Defend the Arctic) 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.
