Peru's ailing ex-president Alberto Fujimori on Tuesday asked the public for forgiveness, two days after receiving a controversial pardon from the country's current leader.

"I am aware that the results of my government were well received on one side, but I admit that I have let down other compatriots, and I ask them to forgive me with all my heart," Fujimori said in a Facebook video filmed from his hospital bed.

The 79-year-old had been serving a 25-year sentence for corruption and human rights abuses committed during his time in office from 1990 to 2000.
