(FILES) -- This file photo taken on May 25, 2010 south of the island of Malta shows environmental group Greenpeace ship Artic Sunrise navigating on the Mediterranean sea during a protest action dubbed "Stop the bluefin tuna massacre - create marine reserves now!", against overfishing of red tuna stocks. Russia in a "surprise move" is to release Greenpeace's Dutch-flagged Artic Sunrise ship, seized last year after a protest against Arctic oil drilling, the environmental group said on Friday.
