Nahrim Mokhtari was arrested hours earlier at the city's international airport when she disembarked from a flight from Paris, on her way to Uruguay.

Miss Mokhtari is the first person to be charged in connection with this attack, although the exact nature of the charges against her have not been disclosed.

Police say she is the former partner of a Brazilian man, Wilson dos Santos, who was detained in Brazil last month. He is believed to have critical information about the bombing in 1994 of a Jewish cultural centre in the Argentine capital which killed 86 people and injured another 300.

Miss Mokhtari is also wanted for questioning over the attack.

Suspected Iranian involvement

Argentina has applied to the Brazilian authorities for Mr dos Santos to be extradited and he is due to be questioned by a Brazilian judge.

Members of the Jewish community in Buenos Aires, as well as US and Israeli intelligence agencies say they believe that both attacks were carried out by Iranian-backed organisations.

Rogelio Cichowolsky, a spokesman for Argentina's Jewish community, said evidence pointed to both bombings being "intimately related, at least from the ideological point of view of the organizers."
