An Argentine court has sentenced Reynaldo Bignone, the country’s last dictator, to 20 years in prison for his part in Operation Condor.

It’s the “first time a court has ruled that Operation Condor was a criminal conspiracy to kidnap and forcibly disappear people across international borders,” The Associated Press reports.

Under this plan, the military dictatorships in Argentina, Chile, Paraguay, Bolivia, Uruguay and Brazil agreed to share information with each other to help track down political opponents and leftists starting in 1975.
