"ROTTERDAM --  Dutch police stormed a Greenpeace ship on Thursday to prevent environmental activists blocking delivery of the first oil from Russia's new Arctic drilling platform reaching port in Rotterdam.

The Rainbow Warrior was crewed by the activists who were detained last year by Russia in the Arctic, the campaign group said. Greenpeace is opposed to drilling in the Arctic Sea which it says risks causing a catastrophe in a fragile ecosystem.

Police said the activists had reneged on an agreement they had made with harbor authorities not to interfere physically with the ship during their protest."
