Japan's push to have activist Paul Watson extradited from Greenland is purely a law-enforcement issue and nothing to do with whaling, Japan's new foreign minister says in rare comments on the case. The co-founder of Sea Shepherd was arrested in Greenland, a Danish autonomous territory, on an arrest warrant issued by Japan, which accuses him of causing damage to its whaling ship in 2010 and injuring a Japanese crew member in clashes off Antarctica. "Japan is requesting from the Danish government an extradition of the suspect," Foreign Minister Takeshi Iwaya says during a press conference in Tokyo. IMAGES AND SOUNDBITES
