Osama bin Laden's son Hamza, chosen heir to the leadership of al-Qaeda, has been killed, American officials said Wednesday.
Questioned by reporters in the Oval Office, US President Donald Trump did not confirm or deny the matter.
"I don't want to comment on it," he said.
But US media, including the New York Times, quoted officials as saying that they had confirmation Hamza bin Laden was killed during the last two years in an operation involving the United States.
Osama bin Laden was killed by US special forces who raided his compound in Pakistan in 2011. Hamza was thought to be in Iran at the time, and documents recovered from the compound indicated that aides had been trying to reunite him with his father.
In February, the State Department said it was offering a reward of up to $1 million for information leading "to the identification or location in any country" of Hamza, calling him a key al-Qaeda leader.
