A Portuguese court official says a former CIA operative convicted of kidnapping an Egyptian cleric in Milan as part of the U.S. extraordinary renditions program is fighting against being sent to Italy to serve the six-year sentence she received in absentia there.

Sabrina De Sousa, who has both U.S. and Portuguese citizenship, was arrested at Lisbon's international airport Monday on a European arrest warrant.

Luis Vaz das Neves, president of the Lisbon court handling her case, told The Associated Press in a telephone interview Friday that De Sousa told a judge she wants to stay in Portugal, where she has been living recently.

He said De Sousa handed both her passports over to the court, which gave her 10 days to provide written legal arguments against her extradition.
