Defne Bayrak, the wife of bomber Humam Khalil Abu-Mulal al-Balawi, said in an interview with The Associated Press that his hatred of the United States had motivated her husband to sacrifice his life on Dec. 30 in what he regarded as a holy war against the U.S.
"My husband was in a struggle against America," she said during the interview at an Istanbul park. "I think the war against America must go on. We must oppose it (U.S.) as it tries to put the entire world under its sovereignty."
Turkish police questioned and released Bayrak on Thursday.
But she says police confiscated a book she had written called "Osama bin Laden, the Che Guevara of the East."
Bayrak, who lives in Istanbul, is an Arabic language translator for some Turkish media outlets.
She told private CNN-Turk television that while in Jordan her husband wrote articles for Jihad Web sites as an outspoken critic of the United States.
"He never digested the U.S. invasion of Afghanistan and Iraq," she said. "He was very disturbed. For example, he was outraged over news that our sisters were raped at Abu Ghraib. He was constantly expressing his anger about the invasion of Muslim lands."
Asked whether she was angry at him for abandoning her with two young daughters, 5-year-old Lina and 7-year-old Leyla, she said: "I can fully understand him, for us the meaning of life is not only this world. God willing, we will be united in the afterlife."
Balawi killed seven CIA employees at a base in Afghanistan on December 30.
A federal law enforcement official said the bomber entered the base by car and detonated a powerful explosive just outside the base's gym, where CIA operatives and others had gathered.
It was unclear whether the explosives were hidden in a suicide vest or belt, but they set off a "significant blast," said the official, who spoke on condition of anonymity due to the sensitivity of the investigation.
Jordanian intelligence officials have said they believed the devout 32-year-old doctor had been persuaded to support U.S. efforts against al Qaeda in Afghanistan.
They say Balawi was recruited to help capture or kill Ayman al-Zawahri, a doctor from Egypt who is bin Laden's right-hand man, according to a counterterrorism official based in the Middle East.
Bayrak has denied that her husband had been recruited to work for the CIA.
