Antarctic researchers rescued from ice-bound ship
Scientific researchers who had been stranded on board an ice-bound vessel in the Antarctic have been airlifted to safety.
A helicopter from a Chinese ship ferried scientists and tourists from the Akademik Shokalskiy to a nearby Australian ice-breaker.
The Shokalskiy has been trapped since Christmas Eve. Its 22 crew remain on board.
