Chilean prosecutors have expanded the charges against former Peruvian president Alberto Fujimori, who is accused of widespread human rights violations during his time in power and is awaiting extradition back to Peru. Fujimori, who ruled Chile between 1990 and 2000, already faces extradition on 11 charges of corruption and human rights, including 25 murders. Chilean public prosecutor Monica Maldonado revealed Tuesday that a charge of usurpation of powers was added as a bases to justify a possible extradition. Maldonado's recommendation is not binding, but it will be the basis for judge Orlando Alvarez to make his ruling over the coming weeks. That decision, in turn, is subject to appeal before the Chilean Supreme Court. The public prosecutor sent her latest report to the judge on Monday, but it was only revealed known Tuesday. Fujimori, 68, is one step away from extradition following a report filed by Maldonado last week. The original recommendations that the former president be extradited to Peru prompted him to be placed under house arrest, to keep him from fleeing.
