Former Army Chief César Milani on Friday reiterated his denial of allegations that he committed human rights crimes during Argentina's 1976-1983 military dictatorship.
The trial is taking place in La Rioja province, where the alleged crimes took place.
Milani gave evidence dressed in full uniform on Thursday and Friday, amid dramatic scenes in court.
He is accused of involvement in the kidnapping and torture of Pedro Olivera (deceased) and his son Ramón, a plaintiff in the case, in March 1977. In a separate case, Milani faces allegations of participating in the kidnapping and disappearance of the soldier Alberto Ledo, whose family members were present in court on Thursday.
