“The loss of Hamza bin Ladin not only deprives al-Qa’ida of important leadership skills and the symbolic connection to his father, but undermines important operational activities of the group,” the President said in the statement.
Trump also said “Hamza bin Ladin was responsible for planning and dealing with various terrorist groups.”
CNN terrorism analyst Paul Cruickshank told CNN at the time that one thing puzzled researchers who are closely tracking al Qaeda: “If Hamza bin Laden has indeed been dead for months, you would expect al Qaeda to have released some form of eulogy before today. The fact they haven’t is highly unusual, given his status in the group.”
The State Department said items seized from the elder bin Laden’s hiding place in Pakistan during the US Navy SEAL raid in 2011 that resulted in his death indicated he was grooming Hamza bin Laden to replace him as al Qaeda’s leader.
Saudi Arabia revoked Hamza bin Laden’s citizenship, official newspaper Um al-Qura reported earlier this year, citing a royal order issued to the Interior Ministry.
