Rescuers say there are no survivors of a helicopter crash in Antarctica.
The Australian Maritime Safety Authority has confirmed that all four Frenchmen aboard the helicopter, which crashed about 100 kilometres from France's Dumont d'Urville research base, are dead.
The AS350 Squirrel helicopter failed to arrive at the base after taking off from the French research ship Astrolabe on Thursday. It was carrying four men - the pilot, a mechanic and two staff from the base.
The maritime safety authority detected the helicopter's distress beacon, but poor weather hampered the search.
Subsequently, an Australian air force plane report seeing debris scattered over 100 metres. Three bodies were seen near the wreckage.
