Donald Trump's government: We have killed Osama bin Laden's son Hamza
A statement gives no further details, such as when Hamza bin Laden, who had become an increasingly prominent figure in the terrorist organisation, was killed or how the US confirmed his death.
The statement says Hamza bin Laden's death "not only deprives al Qaida of important leadership skills and the symbolic connection to his father, but undermines important operational activities of the group".
As leader of al Qaida, Osama bin Laden and others plotted the attacks of September 11, 2001. US Navy SEALs killed him in a raid on a house in Abbottabad, Pakistan, in 2011.
