Chile's Supreme Court has approved the extradition of Peru's former President Alberto Fujimori to face human rights abuses and corruption charges.
Mr Fujimori's arrest came after he tried to relaunch his political career
He is undergoing medical checks and may be sent home within hours.
Mr Fujimori, 69, has been fighting extradition ever since he flew from Japan to Chile in 2005, and is currently under house arrest.
He travelled there in a failed attempt to return to Peru to run in last year's presidential elections.
"We have awarded the extradition," Supreme Court judge Alberto Chaigneau told reporters on Friday.
2 human rights charges:
Sanctioned death squad killings - 1991 Barrios Altos 15 killed
- 1992 La Cantuta 10 killed
5 corruption charges: including
- embezzling $15m
- payoffs to congress members
- illegal wiretapping
He added that the court's decision had been based on two charges of human rights violations and five of corruption.
The ruling is final and no further appeals are allowed.
It reverses an earlier decision by a judge, who said Peru had not presented enough evidence to support the charges.
Peruvian Prime Minister Jorge del Castillo said his government would not politicise the case and pledged that Mr Fujimori would be given a fair trial and treated with dignity.
The human rights charges against the former Peruvian leader date back to the early 1990s, when his government was allegedly responsible for killing civilians in the fight against Shining Path Maoist guerrillas.
One of the alleged massacres was at a poor neighbourhood in Lima in 1991 in which 15 people died.
Relatives of students killed in Lima in 1992 hailed the extradition
The second at a dormitory at La Cantuta University in 1992 in which one teacher and nine students were abducted and killed.
Mr Fujimori says the charges against him are politically motivated, and described his extradition as an opportunity to reconnect with his people and clear his name in Peru.
In his first interview after the ruling, Mr Fujimori told Peruvian radio that he had always tried to do what was best for the country:
"I governed Peru for 10 years, through one of its worst periods, and solved most of the problems the country faced such as terrorism and hyperinflation."
However he acknowledged that "some crass errors" had been made by his administration.
Mr Fujimori - the son of Japanese immigrants - led Peru from 1990 to 2000, and fled the country as his term in office drew to a close amid a corruption scandal.
He initially flew to Japan, where he holds dual nationality and is immune from extradition.
