Peru's government says incarcerated former president Alberto Fujimori has been taken to a hospital for heart surgery.
Government officials say Fujimori was taken from prison to a medical facility in Lima on Friday as his health had deteriorated. He was transported to another hospital on Monday to undergo heart surgery.
Fujimori's eldest daughter, Keiko Fujimori, tweeted on Monday that her father's condition is delicate and his heart problem has worsened.
The former president is 83 years old. In 1990, he became the first Peruvian of Japanese descent to be elected president.
He demonstrated his ability in economic and security policies, but he was criticized in and out of the country for his heavy-handed political stance.
After retiring, Fujimori received a 25-year prison sentence in 2010. He had been found guilty of commanding security forces that killed civilians in the early 1990s.
Peru's Supreme Court granted the former leader a pardon in 2017, citing his deteriorating health, but annulled the move the following year. Fujimori, who was sent back to prison, has been in and out of the hospital recently.
