'He met some people who pretty much brainwashed him in his early 20s. You can call it a cult'

Osama bin Laden's son married Mohamed Atta's daughter?

According to a follow-up article to this one, Osama bin Laden's half-brothers have said they were told that Hamza bin Laden, the son of the former al-Qaeda leader, has married the daughter of Mohammed Atta, the alleged lead 9/11 hijacker. "We have heard he has married the daughter of Mohammed Atta," one of the half-brothers said.

This is strange, since I'd never heard anything about Atta having a daughter. Daniel Hopsicker has reported that Amanda Keller, Atta's alleged girlfriend while he was taking flying lessons in Florida, said he had a son. She said to Hopsicker: "[Atta] told me about this girl he'd dated in France, that had his son. He didn't tell anyone else about that; for some reason he felt he could spill his guts to me. His son was like nine, he said. He said his son was the reason he liked the Beastie Boys so much, 'cause they were his son's favorite band."

Keller, however, apparently never said anything about Atta having a daughter.
