RIYADH, Saudi Arabia - Crown Prince Nayef, the hard-line interior minister who spearheaded Saudi Arabia's fierce crackdown crushing al-Qaeda's branch in the country after the 9/11 attacks in the United States and then rose to become next in line to the throne, has died. He was in his late 70s.
Nayef's death unexpectedly reopens the question of succession in this crucial U.S. ally and oil powerhouse for the second time in less than a year. The 88-year-old King Abdullah has now outlived two designated successors, despite ailments of his own. Now a new crown prince must be chosen from among his brothers and half-brothers, all the sons of Saudi Arabia's founder, Abdul-Aziz.
The figure believed most likely to be tapped as the new heir is Prince Salman, the current defense minister who previously served for decades in the powerful post of governor of Riyadh, the capital. The crown prince will be chosen by the Allegiance Council, an assembly of Abdul-Aziz's sons and some of his grandchildren.
A statement by the royal family said Nayef died Saturday in a hospital abroad. Saudi-funded pan-Arab TV station Al-Arabiya later confirmed he died in Geneva.
Nayef had been out of the country since late May, when he went on a trip that was described as a "personal vacation" that would include medical tests. He travelled abroad frequently in recent years for tests but authorities never reported what ailments he may have been suffering from.
Nayef had a reputation for being a hard-liner and a conservative. He was believed to be closer than many of his brothers to the powerful Wahhabi religious establishment that gives legitimacy to the royal family, and he at times worked to give a freer hand to the religious police who enforce strict social rules.
His elevation to crown prince in November 2011, after the death of his brother Sultan, had raised worries among liberals in the kingdom that, if he ever became king, he would halt or even roll back reforms that Abdullah had enacted.
Soon after becoming crown prince, Nayef vowed at a conference of clerics that Saudi Arabia would "never sway from and never compromise on" its adherence to the puritanical, ultraconservative Wahhabi doctrine. The ideology, he proclaimed "is the source of the kingdom's pride, success and progress."
Nayef had expressed some reservations about some of the reforms by Abdullah, who made incremental steps to bring more democracy to the country and increase women's rights. Nayef said he saw no need for elections in the kingdom or for women to sit on the Shura Council, an unelected advisory body to the king that is the closest thing to a parliament.
His top concern was security in the kingdom and maintaining a fierce bulwark against Shiite powerhouse, Iran, according to U.S. Embassy assessments of Nayef.
"A firm authoritarian at heart," was the description of Nayef in a 2009 Embassy report on him, leaked by the whistleblower site WikiLeaks.
"He harbors anti-Shia biases and his worldview is colored by deep suspicion of Iran," it said. "Nayef promotes a vision for Saudi society under the slogan of 'intellectual security,' which he advocates as needed to 'purge aberrant ideas'" and combat extremism, it added, noting that his was in contrast to Abdullah's strategy emphasizing "dialogue, tolerance of differences, and knowledge-based education that is objectionable to many conservatives."
Nayef, who was interior minister in charge of internal security forces since 1975, built up his power in the kingdom though his fierce crackdown against al-Qaeda's branch in the country following the Sept. 11, 2001 attacks in the United States and a broader campaign to prevent the growth of Islamic militancy among Saudis.
The 9/11 attacks at first strained ties between the two allies. For months, the kingdom refused to acknowledge any of its citizens were involved in the suicide airline bombings, until finally Nayef became the first Saudi official to publicly confirm that 15 of the 19 hijackers were Saudis, in a February 2002 interview with The Associated Press.
In November 2002, Nayef told the Arabic-language Kuwaiti daily Assyasah that Jews were behind the Sept. 11 attacks because they have benefited from subsequent criticism of Islam and Arabs.
Nayef came under heavy criticism in the U.S., especially because he was the man in charge of Saudi investigations into the attack. Criticism grew in the United States that the Saudis were not doing enough to stem extremism in their country or combat al-Qaeda.
Nayef never clashed with Abdullah over reforms or made attempts to stop them - such a step would be unthinkable in the tight-knit royal family, whose members work hard to keep differences under wraps and ultimately defer to the king.
But Nayef was long seen as more favorable to the Wahhabi establishment. In 2009, Nayef promptly shut down a film festival in the Red Sea port city of Jiddah, apparently because of conservatives' worry about the possibility of gender mixing in theaters and a general distaste toward film as immoral.
Nayef, a soft-spoken, stocky man of medium build, was born in 1933, the 23rd son of Abdul-Aziz, the family patriarch who founded the kingdom in 1932 and had dozens of sons by various wives.
Nayef was one of the five surviving members of the Sudairi seven, sons of Abdul-Aziz from his wife Hussa bint Ahmad Sudairi who, for decades, have held influential posts. That made him a half-brother of King Abdullah. Before being appointed interior minister, he held the posts of Riyadh governor, deputy minister of interior and minister of state for internal affairs.
Nayef has 10 children from several wives.
