Woman at center of Berlusconi sex scandal gives new details of "bunga bunga" parties in court

Italian Prime Minister Silvio Berlusconi (L) at Villa Madama in Rome and Moroccan Karima El Mahroug.

MILAN Silvio Berlusconi's private disco featured women dressed not just as sexy nuns and nurses, but also as President Obama and a prominent Milan prosecutor the former Italian premier has accused of persecuting him.

Those are some of the details that emerged Friday during the first public sworn testimony by the Moroccan woman at the center of the sex scandal involving Berlusconi.

Karima el-Mahroug testified Friday at the trial of three former Berlusconi aides charged with recruiting her and other women for prostitution. They deny the charges.

The trial is separate from the one in which Berlusconi is charged with paying for sex with a minor -- el-Mahroug when she was 17 -- and trying to cover it up.
