HELSINKI, Finland, April 24 (UPI) --
Finnish Navy divers began to de-mine the wreckage of a WWII-era Soviet submarine Tuesday, which officials say will take up to four weeks.
The S-2 submarine, sunk on Jan. 2, 1940, will need to have mines and torpedoes removed from its hull. RIA Novosti reported its 50-man crew was lost when it sank in a minefield during the Winter War between the Soviet Union and Finland.
Swedish and Finnish divers discovered the wreckage in the Baltic Sea near the Aland Islands in June 2009, after a nearly 10-year search.
