The Chilean Supreme Court says it will announce Friday its decision in the extradition case of former Peruvian President Alberto Fujimori.

A spokesman for the court made the announcement Thursday.

The five-judge court is to announce whether it has upheld or reversed a July ruling by a Chilean judge who said Fujimori should not be sent back to Peru.

Prosecutors in Peru accuse the former president of corruption, and sanctioning the killing of 25 people by paramilitary squads during his decade-long presidency, which ended in 2000. 

Fujimori is under house arrest in Chile.  After his government collapsed, Fujimori spent five years in exile in his ancestral homeland of Japan before moving to Chile in 2005.
