DHAKA: The Chinese ice-breaker that helped rescue passengers stranded on the Akademik Shokalskiy vessel in Antarctica is now stuck itself.

An Australian ice-breaker carrying the rescued passengers is no longer on standby and is returning to shore, reports BBC.

On Thursday, a helicopter from the Chinese ship, Xue Long, transferred 52 passengers from the Akademik Shokalskiy to the Aurora Australis.

The Russian boat has been trapped by thick floes of ice since 24 December.

"Xue Long`s attempt to manoeuvre through the ice... was unsuccessful. Xue Long has confirmed to the Australian Maritime Safety Authority (Amsa) [that] it is beset by ice," Amsa said in a statement on Saturday.

"The master of Xue Long has confirmed to Amsa that the ship is safe, it is not in distress and does not require assistance at this time," Amsa said, adding that there was no immediate danger to the ice-breaker`s crew.

It is the latest twist in what has become a complicated rescue operation in the Antarctic.

BBC reporter Andrew Luck-Baker, who is on board the Aurora Australis, said: "The irony of the situation is that the Xue Long was originally summoned to break a clear route through the pack ice to the smaller Russian vessel. That was not possible and the large icebreaker is now trapped itself."

Trapped

The Australian Aurora Australis had been asked to remain in open water nearby in case the Xue Long needed help - but Amsa said this was no longer needed and it had been released from its search and rescue mission.

The authority added that the Australian vessel was travelling to the Casey research base on the Windmill Islands, just outside the Antarctic Circle, to complete a re-supply task before continuing to Hobart - the capital of the Australian state of Tasmania.

Andrew Peacock, an Australian doctor and photographer who was rescued from the Russian ship, spoke of his fellow passengers` frustration aboard the Aurora over the latest delay in their journey home, according to the Associated Press.

"So our time down south is not over yet and we are going to be delayed in our return to friends and family by some time yet, which is frustrating," Mr Peacock said before the Aurora was given permission to continue.

The Akademik Shokalskiy, a Russian research vessel, became trapped by thick floes of ice driven by strong winds, about 1,500 nautical miles south of Hobart.

The vessel was being used by the Australasian Antarctic Expedition (AAE) 2013 to follow the route explorer Douglas Mawson travelled a century ago.

Several attempts to break through to the ship by sea - by the Xue Long, Aurora Australis and French-flagged L`Astrolabe - failed because of the thickness of the ice.

The team on board said the ship was stocked with food and was in no danger.
