24 Greenpeace volunteers protest in front of the Gwanghwamun gate, the entrance of the Gyeongbokgung Palace in Seoul.

This protest is part of an emergency Global Day of Solidarity for the 'Arctic 30.’ Tens of thousands of people participate in activities held in over 160 locations in 46 countries throughout the world. A Russian court charged twenty-eight Greenpeace International activists, as well as a freelance videographer and photographer, with piracy this week. The charges follow a peaceful protest against Arctic oil drilling at a Gazprom oil platform in the Pechora Sea.
