Three of the 'Arctic 30' - Kieron Bryan (UK), Ana Paula Alminhana (BRA) and David John Haussmann (NZ) - appear in a St. Petersburg court which is ruling on the extension of their pre-trial detention by a period of three months. The 'Arctic 30' (twenty-eight Greenpeace International activists, as well as a freelance photographer and a freelance videographer) are being detained by Russian authorities following a peaceful protest against oil exploration in the Arctic.
