Around 20 Greenpeace activists boarded a Shell-contracted icebreaker in Helsinki harbour today - locking themselves onto the vessel in a bid to prevent it setting sail for the Arctic.
Greenpeace said they are trying to stop Shell's planned oil drilling in the melting Arctic waters.
It warned that an oil spill off the Alaskan coast would be detrimental for the environment and impossible to clean up because of the region's extreme weather.
The American Institute of Minerals Management Service estimates the probability of an oil spill on the northern Alaskan coast - where Shell wants to start drilling - at one in five.
Attacks such as yesterday's horrific murder in Woolwich didn't happen before the 'war on terror.' It's time we recognised the consequences of the conflicts we've unleashed
