US President Donald Trump has confirmed that Hamza Bin Laden, the son of al-Qaeda founder Osama Bin Laden, was killed in a US operation.
He was officially designated by the US as a global terrorist two years ago.
He was widely seen as a potential successor to his father. Thought to be about 30, he had sent out calls for attacks on the US and other countries.
"Hamza Bin Laden, the high-ranking al-Qaeda member and son of Osama Bin Laden, was killed in a United States counter-terrorism operation in the Afghanistan/Pakistan region," Mr Trump said in a brief statement issued by the White House.
"The loss of Hamza Bin Laden not only deprives al-Qaeda of important leadership skills and the symbolic connection to his father, but undermines important operational activities of the group."
The statement did not specify the timing of the operation.
As recently as February, the US government had offered $1m (£825,000) for information leading to his capture.
