LIMA, Peru — In his first comments since being released from the hospital on a medical pardon that drew wide condemnation, former President Alberto Fujimori of Peru called on the country to set aside its “grudges” in order to unite.

Mr. Fujimori, 79, made the comments on Twitter on Saturday amid an unabating furor over President Pedro Pablo Kuczynski’s decision to free him. The former strongman had served 12 years of a 25-year prison sentence for graft and human rights crimes.

On Twitter, he reflected on the new chapter in his life and urged Peruvians to come together to fight violence and crime.

“In the first hours of this new stage of my life, several dreams invade me constantly, and I would like to share them,” Mr. Fujimori said in a tweet. “I wish for a Peru without grudges, with all of us working toward a superior objective.”
