Hamza Bin Laden, who is believed to be about 30 years old, was officially designated by the US as a global terrorist two years ago.

He married the daughter of Mohammed Atta, who hijacked one of the four commercial aircraft used in the 2001 attacks, and crashed it into one of the World Trade Center towers in New York.

Letters from Osama Bin Laden seized from his compound in Abbottabad where he was killed indicated that he had been grooming Hamza, thought to be his favourite son, to replace him as leader of al-Qaeda, the US state department said.
