A 40-year-old woman who had been taken from her mother at birth in Argentina has been reunited with relatives.

The woman, Adriana, and her relatives were reunited by the human rights organisation Grandmothers of the Plaza de Mayo.

She is the 126th child found by the grandmothers, who campaign for victims of the Dirty War. She was identified after she took a DNA test, and her results matched those of relatives of her parents, who disappeared under Argentina's military rule.

Adriana told a news conference that when the couple who had brought her up died, she was told by someone that she was not their biological child.

She took the tests and more than four months later got a call from the National Commission for the Right to Identity telling her they had information they would like to give her in person.

She was told she was the daughter of Violeta Ortolani and Edgardo Garnier, who disappeared in 1977.

The couple had met as engineering students and were active in a left-wing student group.

Ms Ortolani was detained by the military in December 1976 when she was eight months pregnant.

Adriana was born in captivity in January 1977. Mr Garnier was detained a month later while he was searching for his missing partner and child.

None of the parents were ever seen again. They are two of some 30,000 people who disappeared during military rule.

Mr Garnier's mother never stopped looking for her missing grandchild and has been a key figure in the Grandmothers of the Plaza de Mayo.
