Six Greenpeace activists have been arrested in the Dutch port of IJmuiden after chaining an Arctic-bound Russian oil drilling platform to a dock to try to prevent it from leaving.
Separately, activists from the environmental group climbed on board an oil drilling rig in Norway. Greenpeace regularly calls the Norwegian state-owned Statoil firm an “Arctic aggressor”.
Greenpeace says plans to drill in the Hoop area of the Barents Sea threaten Bear Island, an uninhabited wildlife sanctuary which is home to rare species and occasionally to polar bears.
Oil firms are drilling further north in Norway than ever before as the Arctic ice retreats and recent regulation changes let firms work in areas where winter ice was common just decades ago.
