U.S. scientists rescued from Antarctica

Four U.S. scientists and a contractor stranded in an Antarctic camp have been rescued by the Argentine navy.
They were to be picked up by an American icebreaker, but it wasn't able to reach them due to thick sea-ice.
The five were carrying out research on Joinville Island off the north-eastern tip of the Antarctic Peninsula before being airlifted Monday onto another ice breaker.
They are said to be in good health and will be transported to their own vessel when weather conditions improve.
