Argentina ? Argentina said Tuesday it had sent Spain an extradition request for former President Isabel Peron, who is wanted for questioning about a disappearance that occurred when death squads terrorized the country during her rule.

The Foreign Ministry said extradition papers were sent at the request of Federal Judge Raul Acosta, who last month ordered Peron detained for questioning about the February 1976 disappearance of leftist Hector Aldo Fagetti Gallego.

The third wife of three-time president Juan Domingo Peron, Isabel Peron ruled Argentina after the strongman’s death for 20 chaotic months until a March 1976 coup.

Isabel Peron, who has lived in quiet exile in Madrid in the decades since her ouster, was detained briefly last month by authorities in Spain. She was freed after three hours, pending an extradition request from Argentina. The court ordered Peron to appear at a police station every 15 days.
