Dozens of ships that had been trapped in ice in the Baltic Sea off Stockholm have been freed. A spokesman of the Swedish maritime authorities said the last vessel was rescued from the waters between the capital and the Aaland Islands early today. Icebreakers had to be used to free the ferry Amorella, which had 943 passengers and crew on board. <br/><br/>There was a minor collision between the Finnfellow and the Amorella when they tried to manoeuvre in the ice yesterday, but there was no major damage reported by either vessel. Two other ferries, the Isabella and the Finnfellow, managed to break free yesterday. The Swedish Maritime Administration said, at least 26 ships are awaiting help further north in the Bay of Bothnia.
