Paraguayan human rights groups say they've identified the remains of an Italian woman and a Paraguayan man who were seized by authorities during a bloody regional crackdown on dissidents in the 1970s.

Rights activist Rogelio Goiburu says the Rafaelli Filipazzi and Miguel Angel Soler were identified by DNA tests.

Soler was secretary-general of the Paraguayan Communist Party when he was captured in the capital of Asuncion in 1975.

Filipazzi was an Italian socialist living in Argentina. She vanished in Uruguay in 1977, a victim of Operation Condor in which dictatorships in several countries joined to hunt down dissidents across borders.

The remains of both were found at a former police base in Asuncion.
