A Greenpeace protestor displays a sign as about others move in to climb on top of the offshore oil rig, the Leiv Eiriksson, off Istanbul, Turkey, on April 22. The vessel is sailing from Turkey to Greenland for Cairn Energy, which plans to drill four wells in Baffin Bay off Greenland’s west coast this summer. The Associated Press reported that in spite of the incident, the vessel continued sailing through the Dardanelles and into the Aegean Sea off Greece with protestors still clinging to the rig. They abandoned their protest after 12 hours due to bad weather. (PHOTO BY MARKEL RENDONDO/ GREENPEACE)
