A group of 80 activists supported by the Greenpeace flagship Rainbow Warrior are attempting to stop Gazprom’s oil tanker Mikhail Ulyanov from delivering the first ever oil from icy Arctic waters. This is the same oil 28 Greenpeace activists and two journalists were imprisoned in Russia for protesting against last year. Six were British. They are calling for a ban on offshore oil drilling in the Arctic and an urgent switch to new sources of energy.
