[JURIST] The Spanish government on Thursday extradited pilot Julio Alberto Poch to Argentina to face trial for his alleged role in the nation's 1976-83 "Dirty War" [GlobalSecurity backgrounder; JURIST news archive]. Poch was a navy officer at Argentina's Naval Mechanics School [backgrounder, in Spanish], one of the most notorious detention centers of the military dictatorship, and is believed to have piloted flights known as "death flights," which were used to dump the military junta's political opponents into the Plata River and the Atlantic Ocean. Poch holds dual Dutch and Argentine citizenship, which had protected him from earlier attempts at extradition, but he was arrested and imprisoned last September when he landed in Valencia while en route to the Netherlands. A Spanish court agreed to his extradition [JURIST report] in January, finding that there are adequate measures in place to guarantee that Poch will receive a fair trial in Argentina. Poch continues to deny the charges against him [AP report] and faces a Friday court hearing.
