Wife of 'wanted terrorist' al Libi: He left al Qaeda Official: Commandos from the elite U.S. Army Delta Force conducted the raid Abu Anas al Libi's wife says some of the men in the raid seemed to be Libyans The operation was a "masterpiece," Libyan counterterrorism analyst says Tripoli, Libya (CNN) -- The wife of an accused al Qaeda operative captured by U.S. forces told CNN that masked men ambushed her husband when he was on the way home from morning prayers. While U.S. Defense Secretary Chuck Hagel called Abu Anas al Libi "one of the world's most wanted terrorists," al Libi's wife described him a different way in an exclusive interview with CNN on Sunday. Umm Abdul Rahman called al Libi an innocent man, adding that he left al Qaeda in 1996 and had no connection to the twin 1998 bombings at U.S. embassies in Kenya and Tanzania. "I am sure of what I am saying -- he did not take part in any bombing anywhere in the world," Rahman said. He was a member of al-Qaeda and he was personal security for (Osama) bin Laden -- that's true -- but he did not take part in any operation. Al Libi was among those indicted for the embassy attacks by a federal grand jury in New York, and U.S. officials and terrorism analysts hailed news of his capture. Meanwhile, Libya's interim government distanced itself from the operation and called the U.S. capture a kidnapping. Rahman told CNN she didn't know who had taken her husband -- only that the raid she watched happen from her Tripoli home happened very quickly. Al Libi was returning to his house at about 6:30 a.m. Saturday (12:30 a.m. ET) when a group of at least 10 men in four vehicles surprised him, his wife told CNN. Some of the men were wearing masks, while others weren't, she said. Those men looked like Libyans to her and they spoke Arabic with Libyan accents, she said. What I saw were Libyans. Maybe they had Americans with them, but I didn't see them because there was more than one car. They say there were 10 people involved, but I believe there were more than 10," Rahman said. I couldn't count them because there were many of them. I can't confirm if they were Americans or not, but what I saw were Libyans.  Elite team involved in capture On Sunday, a U.S. official said commandos from the elite U.S. Army Delta Force had snatched the 49-year-old al Qaeda operative. Tripoli has requested an explanation from Washington about the raid, the country's state news agency reported Sunday. The mission was conducted with the knowledge of the Libyan government, said one U.S. official. A U.S. official told CNN that he was taken to a U.S. Navy warship after his capture. "It's a masterpiece how someone can craft such an operation," said Libyan counterterrorism analyst Noman Benotman, who is also a former jihadist associate of al Libi. Benotman is president of the Quilliam Foundation, a London-based counterterrorism think tank. He is also a former senior member of the Libyan Islamic Fighting Group, which al Libi joined in the mid-1990s before gravitating back toward al Qaeda. Al Libi had been living in that still unsettled nation, more or less in the open, for more than a year despite his alleged associations. According to Benotman, it is unlikely he was still playing an active role for al Qaeda. His wife agreed, saying he was living a normal life, was not in hiding and had reapplied for a job with the oil ministry. She said he has a severe case of hepatitis C and she worries about his health. Al Libi has been all around the globe -- Afghanistan, Pakistan, Sudan, Kenya, Britain, Iran and beyond -- making friends with some of the world's most notorious terrorists and enemies with the United States and its allies. On Saturday, his odyssey ended where it began: in his homeland of Libya. He eventually will be taken to New York, a source with knowledge of the capture and proceedings told CNN, though the exact timing is unclear. Edith Bartley lost both her father, Julian Bartley, and her brother, Julian Jr., in the attack in Nairobi, Kenya. Her father was the U.S. Embassy's counsel general; her 20-year-old brother was an intern there. "We know that this is a firm signal around the globe that as our government is still wading through a standstill right now, that we are still vigilant as a country and focused on international terror, and we're not going to step down at all," Bartley told CNN's "New Day Sunday." Bartley said while she was relieved when Osama bin Laden -- also indicted in the embassy attacks -- was killed in 2011, she's also happy that al Libi was taken into custody. CNN's Nic Robertson, a veteran of covering al Qaeda, said al Libi's arrest is a "huge deal." "He's a big player in al Qaeda (and) in one of the key target areas, in the north of Africa," he said. The FBI's page on al Libi -- part of its roster of "Most Wanted Terrorists" and noting the $5 million reward being offered for information leading directly to his apprehension -- says that he is accused in a "conspiracy to kill United States nationals, to murder, to destroy buildings and property of the United States, and to destroy the national defense utilities of the United States." Born Nazih Abd al Hamid al Ruqhay, al Libi joined al Qaeda soon after its founding, as the terrorist organization built up its presence in Afghanistan and Pakistan. His wife denied that he had any role in any bombing and said that after he returned to Libya in 2011 during the revolution, he had been asking the Libyan government to help him clear his name. She did admit that he had belonged to al Qaeda, but said he was a personal guard for bin Laden until he left the terror group in 1996. Authorities uncovered a document that became known as the "Manchester Manual" -- hundreds of pages of guidance on carrying out a terrorist campaign. Among them: a document that called for "attacking, blasting and destroying" embassies. Western intelligence had tracked his movements in Tripoli, and had even taken surveillance photos. Western intelligence sources said that there was concern that al Libi was working to establish an al Qaeda network in the North African nation, but no evidence has since materialized that he continued to be involved in terrorist operations after he returned to Libya. In December 2010, before the outbreak of the unrest that ended with Moammar Gadhafi's death, Libyan authorities told a United Nations committee that al Libi had returned, even giving a Tripoli address for him. And one Western intelligence source said al Libi appears to have been in Libya in the spring of 2011, when the civil war was in full swing. Family members told CNN al-Libi returned to Tripoli in 2011 to take part in the revolution against Gadhafi. His wife, four sons and daughter had arrived from Iran the previous year. Al-Libi's sons and wife say they believed they were under surveillance over the past two years in Libya and expected anything -- even a drone strike. But Saturday's raid still came as a surprise. There was no longer any talk about him in the media, so we felt somewhat reassured. He even stopped taking his weapon or his sons with him or hiring private security -- he was living his life normally," Rahman said. Counterterrorism analysts told CNN in fall 2012 that al Libi may not have been apprehended at the time because of the delicate security situation in much of Libya, where ex-jihadists -- especially those who once belonged to the Libyan Islamic Fighters Group -- held considerable sway after the campaign against and ultimate ouster of longtime leader Gadhafi. The fact that there's no extradition treaty between Libya and the United States further complicates matters.
