Protests were held in more than 260 cities worldwide on Saturday to mark two months since the detention of the Greenpeace “Arctic 30” for protesting gas drilling by Russia. The 28 activists and two journalists are facing charges of “hooliganism” which carry up to seven years in prison. Saturday’s rallies focused on urging Russia’s state-controlled oil company, Gazprom, and its partner, Shell, to back calls for the Arctic 30’s release.
