Officials said Friday that jailed Saudi Arabian entrepreneur Adnan Khashoggi may agree to be extradited to the United States.

Khashoggi, 53, was arrested Tuesday by Swiss police on a warrant issued in New York, where he was indicted March 9 for alleged illegal property dealings with former Philippine president Ferdinand Marcos.The Saudi Arabian arms dealer, once a multibillionaire but now in financial difficulty, also was charged with allegedly selling valuable paintings that Manila says were stolen by Marcos when he was ousted in 1986.

The formal U.S. extradition request had not arrived by Friday, which meant there would be no new developments before next week, a Swiss Justice Ministry spokesman said.

Khashoggi has not made his intentions known on extradition through his American lawyer, Frank P. Morse, or his Swiss lawyer Ralph Zloczower, the spokesman said.
