Dr Francesca Lessa interviewed on the BBC on the day of the Operation Condor trial verdict

Dr Lessa, based in Buenos Aires to monitor the Operation Condor trial, was interviewed this week by the BBC. The trial verdict in this historic prosecution will be delivered this afternoon in the Comodoro Py courthouse.

Operation Condor was a campaign of state-sponsored terror organised by South American dictatorships in the 1970s, designed to hunt down political opponents across the continent.
