A Chinese icebreaker that helped rescue passengers from a Russian ship in Antarctic ice has found itself stuck in heavy ice.
The Australian Maritime Safety Authority said the "Snow Dragon," which helped to ferry 52 scientists and tourists from the ice-bound Russian ship "Akademik Shokalsky" to an Australian supply ship late on January 2, now has concerns about its own ability to move.
It said the icebreaker will attempt to move through the pack ice when tidal conditions are most suitable, during the early hours of January 4.
The Australian icebreaker carrying the rescued passengers, the "Aurora Australis," will remain on standby in open water in the area as a precautionary measure.
The "Akademic Shokalsky" has been trapped in thick ice since December 24.
