Former Argentine junta leader Reynaldo Bignone has been sentenced to 20 years in prison for crimes committed under Operation Condor - a conspiracy between South America's dictators.
Bignone and 14 other military officers were found guilty by a court in Argentina after a three-year trial.
Many left-wing activists were kidnapped and killed in Argentina, Uruguay, Brazil, Chile, Paraguay and Bolivia.
Operation Condor was secretly launched in the 1970s.
