A Cypriot prosecutor has tried to cast doubt on an Egyptian hijacker's defense that his opposition to Egypt's military-backed government could put his life at risk if he's extradited.

The hijacker's ex-wife, Marina Paraschou, testified as a prosecution witness during an extradition hearing Friday that Seif Eddin Mustafa had been in jail for most of their nine years marriage, but that his time behind bars in Egypt, Syria and Yemen was not because of his politics.

Mustafa's lawyer says his client fears torture or death if extradited because of his political beliefs.

But under cross-examination, Paraschou said that she knew Mustafa worked for the Palestine Liberation Organization and that he had twice been imprisoned by the Egyptian army for desertion.
