The citizenship of Hamza bin Laden has been revoked by Saudi Arabia authorities after the United States offered a reward of up to $1 million (£756,000) for information relating to Osama bin Laden's son.
According to the BBC, Hamza is believed to be based near to the Afghan-Pakistani border and is said to be an emerging leader of the Islamist militant group al-Qaeda.
His father - Osama - masterminded the 9/11 attacks in 2001 which killed 3,000 people when a series of four passenger airliners were hijacked by 19 al-Qaeda terrorists.
Osama bin Laden was killed in a compound in Abbottabad, Pakistan, during a US military raid 10 years later.
Following his death, Hamza released audio and video messages calling on supporters to attack the US in revenge.

The US State Department said that the $1 million reward would be paid for help locating Hamza bin Laden in any country and is part of its 'rewards for justice' programme.
Assistant Secretary for Diplomatic Security Michael Evanoff told the BBC: "We do believe he's probably in the Afghan-Pakistan border [sic] and... he'll cross into Iran. But he could be anywhere though in... south central Asia."
Hamza is believed to be around 30 years old with the US state department saying that he married the daughter of Mohammed Atta, who hijacked one of the aircraft used in the 2001 attacks - specifically a plane that crashed into one of the World Trade Center towers in New York.
The US State Department also added: "Hamza bin Laden ... is emerging as a leader. He has released audio and video messages on the Internet, calling on his followers to launch attacks against the United States and its Western allies, and he has threatened attacks against the United States in revenge for the May 2011 killing of his father by US military forces."
