Saudi Arabia has stripped citizenship from Hamza bin Laden, the son of slain al-Qaeda leader Osama bin Laden, the interior ministry said in a statement published by the official gazette.
The Saudi decision was made by a royal order in November, according to a statement published in the Um al-Qura official journal.
The US State Department said on Thursday it was offering a reward of up to $1 million for information leading "to the identification or location in any country" of Hamza, calling him a key al-Qaeda leader.
According to Agence France Presse, his location has been the subject of speculation for years with reports of him living in Pakistan, Afghanistan, Syria and Iran.
In 2015, bin Laden released an audio message urging militants in Syria to unite, claiming that the fight in the war-torn country would pave the way to "liberating Palestine,@ it said.
Hamza, who according to Washington is around 30, has threatened attacks against the US to avenge the 2011 killing of his father -- who was living in hiding in the Pakistani garrison town of Abbottabad -- by US special forces.
He is known to have married the daughter of Abu Mohammed al-Masri and not Mohammed Atta as claimed.
