Former Peruvian President Alberto Fujimori is being extradited to Peru today to face human rights and corruption charges related to his 1990-2000 presidency -- apparently the first time a former head of state has been extradited to his home country to face prosecution on human rights charges.

A five-judge Supreme Court panel Friday approved Peru's request that Fujimori be returned to stand trial on charges that he approved a clandestine death squad, illegally tapped telephones, illegally transferred public money to his spy chief, bribed legislators for support and journalists for favorable coverage, and illegally seized potentially incriminating documents, videotapes and other material.

Fujimori was put on a small plane in Santiago Saturday morning that belongs to the Peruvian National Police. He was expected to arrive to Lima late in the afternoon and be sent immediately to a high-security prison.

Chile had up to three months to cary out the extradition, but the government of Chilean President Michelle Bachelet wasted no time in getting him off of Chilean soil.

Fujimori told the television news channel CNN en Español on Friday that his extradition to Peru was part of his plan to return to his native country with fewer charges against him.

''This step was considered by me necessary, indispensable,'' Fujimori said. ``Each one of these accusations will be clarified totally in the process.''

A 1932 extradition treaty between Chile and Peru allows Fujimori to be tried in Peru only for the seven cases that Chile's Supreme Court approved, and not for dozens of other crimes he allegedly committed. Peruvian prosecutors can add more charges only if Chile's Supreme Court approves them as part of another extradition order.

Fujimori will be tried in a special federal court with possible appeal to Peru's Supreme Court, said Monica Feria, an international law expert from Peru. He faces 20 years in prison if he's convicted as the intellectual author of the murders attributed to the death squad and lesser sentences for corruption charges.

The Chilean court's decision, which can't be appealed, ends almost two years of uncertainty that began when the 69-year-old showed up in Chile by surprise in November 2005 on a private plane from Japan, where he'd been in exile since 2000.

CELEBRATION

Human rights advocates and attorneys for Peru celebrated the decision as the first time a former head of state has been extradited back to his country to face prosecution on human rights charges.

''The message this case is sending to the world is that the space for impunity for perpetrators of gross human rights violations, especially for former heads of state, is narrowing,'' said José Miguel Vivanco, executive director of the Americas wing of U.S.-based Human Rights Watch.

The decision also ended Chile's record of rejecting extradition requests. Before Fujimori's arrival, Chile had refused to extradite two men, Eduardo Calmell del Solar and Daniel Borobio, whom Peru had accused of illicit association and influence-peddling during Fujimori's reign.

Gisela Ortíz, the sister of a murdered Peruvian college student, called Friday's ruling an important step in a long struggle to bring Fujimori to justice. Her brother Enrique was abducted from his dormitory in July 1992 by the Colina Group -- a paramilitary death squad that's been blamed for the murders of 25 suspected dissidents during the early 1990s -- and later found dead.

''This finishes one chapter, but it's the beginning of another big chapter for our country,'' Ortíz said. ``It will be a test for all of us Peruvians.''

SURPRISE VICTORY

Fujimori, an unknown agronomist who came out of nowhere to win the presidency in 1990, was admired for taming hyperinflation and defeating the leftist Shining Path guerrilla group, which had brutally battled Peru's government throughout the 1980s.

Yet he also closed the country's Congress in 1992 and resorted to bloody tactics to weed out suspected dissidents.

Facing corruption accusations, he fled to Japan in 2000 during an official trip to Asia and faxed in his resignation. As a Peruvian of Japanese descent, he was able to claim Japanese citizenship, and this year he made an unsuccessful bid for a seat in Japan's senate while he was in Chile awaiting extradition to Peru.

His return threatens to complicate the prospects of Peruvian President Alan Garcia, who depends on legislators from Fujimori's party to pass legislation.

''There's fear of Fujimori's return in many sectors here, both in the left and the right,'' La Republica newspaper columnist Mario Munive said. ``It will totally change the shape of politics here and will complicate things for Garcia, because the Fujimoristas are very close allies to the president.''

Friday's decision reversed a ruling in July by Chilean Supreme Court Judge Orlando Alvarez that had rejected all the charges of the extradition request. Alvarez had argued that Peruvian attorneys had failed to prove Fujimori's connection to the crimes, and that the statue of limitations on some charges had run out.

The Supreme Court panel, however, found that witness testimony and other evidence suggested that Fujimori had a role in seven of the 13 cases brought against him.
