Greenpeace activists arrested
All activists from Greenpeace who boarded an icebreaker have now been arrested. The ship was off the coast of Sweden, on its way to assist Shell's search for oil in the Arctic.
The six activists, including at least one Swede, went aboard early on Thursday morning, while the Finnish state-owned icebreaker Nordica was off the south-east coast of Sweden's Blekinge.
Police and coastguards arrived to assess the situation, and Nordica has now been taken to the port of Karlskrona, where police will attempt to remove the activists, two of whom have locked themselves into the ship.
This is the second time this week that activists have tried to stop the ship. Greenpeace says that drilling for oil in the Arctic will cause major environmental damage.
