Osama and Yeslam shared the same father, Mohammed, a wealthy construction magnate who had more than 50 children. It's not clear if the two half-brothers were close, but Osama has been described as the black sheep of the family.

Mohammed bin Laden had close ties to the Saudi royal family.
The Bin Laden family are known for building many of Saudi Arabia's roads, mosques, and palaces, according to Reuters.
According to a 2001 article in The New Yorker, Yeslam was the head of his family's European holding company, the Saudi Investment Company.
Yeslam also told The Telegraph in 2004 he had not seen Osama for more than 20 years.
"He left for Afghanistan and several years later, I left the kingdom for Switzerland," Yeslam told the British newspaper. "I have had no contact with him whatsoever since then."

She has claimed that if Democratic presidential nominee Joe Biden is elected, America would be at risk of another September 11-style attack.
"ISIS proliferated under the Obama/Biden administration, leading to them coming to Europe," bin Ladin told the Post.
"Trump has shown he protects America and us by extension from foreign threats by obliterating terrorists at the root and before they get a chance to strike."
Bin Ladin has also referred to Biden as "Sleepy Joe," a nickname Trump frequently uses.
She recently shared a letter on her website, in which she called Trump "the only leader who can save us from a bleak future."

"With President Trump at her helm, America stands a chance of restoring her principles, pride, independence and true place in the world as a beacon for liberty and hope for all," she wrote in the letter.
"This to me, is what 'Make America Great Again' means. Looking back at your country's foundation, and preserving what makes it truly GREAT. But also knowing that the best is yet to come."
"All the above achievements will be torpedoed with a Biden/Harris presidency, and the dream of America's enemies to see her weak and on her knees would be fulfilled."
She has also tweeted about "Obamagate," a groundless conspiracy theory pushed by Trump and his allies in the past.

The theory claims that former President Barack Obama tried to sabotage Trump's presidency in his final weeks. Trump has repeatedly name-dropped the theory in the past.
According to bin Ladin's Twitter page, she has had the account since 2010, but her tweets only go back as far as February 2019, and most of her tweets were written in the last six months alone.
Business Insider has contacted bin Ladin for comment.
