Climbers of the environmental group Greenpeace hang banners on the Sagrada Familia, demanding the release of 30 activists arrested and jailed by Russia for staging an open-sea protest against Arctic oil drilling, in Barcelona on November 8, 2013. Several activists in mid-September attempted to scale Russia’s Gazprom oil platform in the Pechora Sea, part of the Barents Sea, in protest of its exploration in the Arctic. They were charged with piracy — which carries a sentence of up to 15 years — after their ship was boarded by Russian coastguards on September 19, and have been placed in pre-trial detention until November 24.
