WASHINGTON: The United States on Thursday (Feb 28) offered a US$1 million reward for information on a son of late Al-Qaeda leader Osama bin Laden, seeing him as an emerging leader of the extremist network.
The location of Hamza bin Laden, sometimes dubbed the "crown prince of jihad," has been the subject of speculation for years with reports of him in Pakistan, Afghanistan or under house arrest in Iran.
"Hamza bin Laden is the son of deceased former AQ leader Osama bin Laden and is emerging as a leader in the AQ franchise," a State Department statement said, referring to Al-Qaeda.
The State Department said that it would offer US$1 million for information leading to his location in any country.
Hamza, who according to the United States is around 30, has threatened attacks against the United States to avenge the 2011 killing of his father, who was living in hiding in the Pakistani garrison town of Abbottabad, by US special forces.
US intelligence agencies increasingly see Hamza as a successor to his father for the mantle of global extremism, especially as the even more extreme Islamic State group is down to its last sliver of land in Syria.
In 2015, Hamza released an audio message urging militants in Syria to unite, claiming that the fight in the war-torn country paves the way to "liberating Palestine."
And in a message a year later, following in the footsteps of his father, he urged the overthrow of the leadership in their native Saudi Arabia.
Osama bin Laden's three surviving wives and his children were quietly allowed to return to Saudi Arabia after his killing.
But Hamza's whereabouts have been a matter of dispute. He is believed to have spent years along with his mother in Iran, despite Al-Qaeda's strident denunciations of the Shiite branch of Islam that dominates the country.
Observers say that the clerical regime in Tehran kept him under house arrest as a way to maintain pressure on rival Saudi Arabia as well as on Al-Qaeda, dissuading the Sunni militants from attacking Iran.
One of Hamza's half-brothers told The Guardian last year that Hamza's whereabouts were unknown but that he may be in Afghanistan.
He also said that Hamza married the daughter of Mohammed Atta, the lead hijacker in Al-Qaeda's Sep 11, 2001 attacks on the United States that killed some 3,000 people and sparked the US intervention in Afghanistan.
