On Saturday the White House said he was killed in “a United States counterterrorism operation in the Afghanistan/Pakistan region”. It did not say when.

Reuters reported that an unnamed US official said Hamza was killed “months ago” and Trump was briefed at the time.

Bin Laden, who was believed to be aged around 30, had been seeking to lead a resurgence of al-Qaida, which has been eclipsed among jihadist terrorist groups by Islamic State. The US state department designated him as a terrorist in 2017.

“[Al-Qaida was] clearly grooming him to be a next generation successor,” Peter Bergen, director of the international security programme at the New America foundation, told the Guardian in July.
