Protesters hold signs and ask for the protection of the Arctic and the release of the 'Arctic 30' during a protest march from the Russian embassy to the Peace Palace.
Tens of thousands of people have taken part in an emergency global day of solidarity with the 'Arctic 30' in well over 80 cities in 50 countries throughout the world. 28 Greenpeace International activists, including a freelance videographer and photographer, were charged with piracy this week by a Russian court, following a peaceful protest against Arctic oil drilling at a Gazprom oil platform in the Pechora Sea.
