Geneva The only family member to talk openly about Osama bin Laden describes him as pious and merciless, a man so driven by his beliefs that he once denied a water bottle to his own infant son in the heat of the Saudi desert.
Carmen Binladin, the terrorist leader's sister-in-law, says bin Laden's religious conviction was so admired by his family that she refuses to believe his relatives have stopped supporting him, as they claim.
In a new book and during an extensive interview with The Associated Press, she said a turning point in her life was a bin Laden family gathering in Taef, Saudi Arabia, one sweltering day in the mid-1970s.
Bin Laden's son began crying for water, she said, but the elder bin Laden refused to allow the baby to be given a water bottle, saying the boy should be fed water with a spoon because of Muslim teachings.
"It was not as if he didn't care about the child. But to him, the baby's suffering was less important than a principle which he probably imagined stemmed from some seventh-century verse in the Quran," Binladin said in her book, "Inside the Kingdom."
'They are very close'
The respect her husband and Osama's 23 other brothers accorded him by accepting his decision helped persuade her to leave Saudi Arabia, Binladin says.
"From what I have seen and what I have read, I cannot believe that they have cut off Osama completely," Binladin said on the eve of a visit to the United States to promote her book, to be published in English on Wednesday.
She said some of Osama's sons were still in Saudi Arabia, working for the Bin Laden Group construction company, which the 25 brothers inherited from their father, Mohammed bin Laden.
"Osama is not the only religious (bin Laden) brother in Saudi Arabia," she said. "And I cannot believe that some of the sisters (don't support him.) They are very close to Osama."
She said there may also be ties between Osama and the royal family, despite his criticism of the royals for their support of the United States and alleged corruption within the government.
"The bin Ladens and the princes work together, very closely," Binladin wrote. "They are secretive, and they are united. They have been inextricably linked for many decades through close friendships and business ventures."
Fleeing Saudi Arabia
Binladin married Yeslam, one of Osama's brothers, in 1974 and lived in Saudi Arabia for nine years. She said she wrote the book mainly to explain to her daughters why she had returned with them to Switzerland. Her divorce from Yeslam is still unresolved after 14 years.
Binladin is the daughter of a Swiss father and an aristocratic Iranian mother.
Her book has already appeared in 16 languages and 18 countries. But she said she had held off publishing it in the original English because of fears about how it would be received in the United States, where she lived for a time in the 1970s.
She and her estranged husband intentionally spell their name differently from the rest of the family and Osama.
She said her time in Saudi Arabia gave her an understanding of the closeness of the bin Laden family, which lived in the 1970s clustered in a group of houses on Jeddah's outskirts.
Women were required to wear a robe covering their faces and bodies whenever they went outside the home or encountered any males outside their immediate family.
"One day, Yeslam's younger brother Osama came to visit," she said in the book. "When the doorbell rang, I stupidly, automatically, answered it myself, instead of calling for the houseboy."
She said she recognized Osama and asked him in.
"But Osama snapped his head away when he saw me," she said.
He waved her aside, muttering something in Arabic, "but I truly didn't understand what he meant."
A nephew with Osama explained that he was forbidden to look at her face.
She said she doubted accounts that Osama had been a playboy as a teenager in Beirut and thinks the story may have been about another brother.
"As far as I know, Osama was always devout. His family revered him for his piety," she said.
Osama started putting his beliefs into action during the guerrilla war against the Soviet occupation of Afghanistan.
When Iraq invaded Kuwait in 1990, Osama was outraged that U.S. forces might use Saudi Arabia as a base. He then started making "incendiary statements" against alleged corruption of the Saudi ruling family, and he was forced to leave.
