The child survivor of the Yemenia jet crash which killed 152 today spoke of her ordeal as she flew back to France for an emotional reunion with her father.

Bahia Bakari told a French government minister that she felt something 'like electricity' before the crash.

'She says instructions were given to passengers and that then she felt something like electricity ... as if she had been a bit electrocuted,' France's government minister for cooperation, Alain Joyandet, who flew back to Paris with Bahia today, said.

'And suddenly there was this big sound. She found herself in the water - and you know the rest.'

Bahia lost her mother in the tragedy and only survived by clinging on to debris for more than 12 hours before search teams spotted her in rough seas.

Astonishingly, the 14-year-old is barely able to swim and did not have a life jacket.

She was only told today that her mother was dead. An uncle who visited her yesterday at a Comoros hospital was too heartbroken to break the news - and told her that her mother was recovering instead.

Bahia's father, Kassim, met the plane, saying he was relieved and overjoyed to see his daughter even as he mourned his wife.

'It was very powerful,' he said of his reunion with Bahia. He said he asked her,''How are you? Was the return trip OK?' ... We joked a little, the two of us.'

Joyandet praised her strength and courage.

'It's an enormous message that she sends to the world ... almost nothing is impossible,' he said. 'We will do everything we can to help her.'

'I am torn between relief and sadness. I am happy to see my daughter but her mother did not come back,' Bahia's father, Bakari Kassim, said shortly after she landed at Roissy Airport in Paris.

Bahia had been sedated for the flight and appeared groggy as she arrived back in France.

She was flown home on a French government jet from the the Indian Ocean archipelago of Comoros.

Doctors in Comoros, who marvelled at Bahia's escape with little more than cuts, bruises and a fractured collar bone, said she was discharged on her father's request.

'It was on the demand of her father in France. The girl was regaining her spirit and was in a satisfactory physical state,' Dr Jean Youssef, lead doctor at the disaster unit on Grand Comore, said.

Youssef said Moroni's El Marouf hospital lacked the facilities needed to properly scan the teenager's body for any internal damage.

Rescuers have failed to find any of the remaining 152 passengers and crew since the Yemenia Airbus A310 crashed in rough weather off Comoros in the early hours of Tuesday.

American and French military aircraft continued to scour the crash site on Thursday to locate the wreckage, thought to be in waters up to 1,600ft deep.

Rescuers suspect many of the dead remained trapped inside the doomed plane and say the search effort should focus on finding the wreck.

'Everything leads us to believe that the bodies of the victims remain inside. In two days we haven't found a body, any large pieces of debris or suitcases floating on the water,' disaster centre member Ibrahim Abdourazak said.

The cause of the crash is still unknown.

The French defence ministry have denied that the black box recorder, which will give vital clues to the crash, has been located despite earlier reports to the contrary.

The aircraft, which was on the final leg of a trip from Paris and Marseille, was the second Airbus to crash into the sea in a month.

The airline said there were 75 Comoran passengers on board, along with 65 French nationals, one Palestinian and one Canadian. The crew comprised of six Yemenis, two Moroccans, one Indonesian, one Ethiopian and a Filipina.
