(QHA) - A Russian ship and a Chinese icebreaker trapped in Antarctic ice have finally broken free after being stuck for several days, Euronews reports. A crack in the ice has appeared after a change in wind direction. The Russian research vessel was carrying 52 passengers when it became blocked. But a Chinese ship which sailed to its rescue found itself stuck in heavy ice on Friday. The tourists and scientists on board were eventually ferried off by a Chinese helicopter to an Australian ship. The ‘Akademik Shokalskiy’, left New Zealand at the end of November to commemorate the 100th anniversary of an Antarctic journey led by Australian explorer Douglas Mawson.
