Washington: Al Qaeda's Hamza bin Laden was very threatening to the US, President Donald Trump said on Thursday as he refrained from making any comment on news reports about the death of Osama bin Laden's son.

"I can't comment about that. But he was very threatening to our country. He was saying very bad things about our country," Donald Trump told reporters at the White House when asked if the United States had any role in the death of Hamza bin Laden.

The US media on Wednesday, quoting unnamed officials, reported that Hamza bin Laden was killed during the first two years of the Trump administration. There has been no official confirmation of it from the United States.

"If confirmed, his death represents another blow to Al Qaeda, whose ranks were hollowed out by relentless American attacks and by the rise of ISIS," said The New York Times, which was the first US publication to report about it.

"But I can't comment," Donald Trump said when asked about the death of the successor of Osama bin Laden.

"But I will say, Hamza bin Laden was very threatening to our country, and you can't do that. Anything beyond that, I have no comment," Donald Trump said.

According to The New York Times, Hamza bin Laden was not older than 30. "Because he carries the most famous name in terrorism, the younger bin Laden is able to draw on the devotion that jihadists around the world feel for his father," the US daily reported.

For these reasons, Al Qaeda hoped that Hamza bin Laden would be a unifier, appealing not just to the group's base but also to the recruits it lost to ISIS, the US daily stated.

According to the New York Times, Hamza bin Laden had been killed in operation during the first two years of the Donald Trump administration even before the State Department had announced a 1 million US dollars reward for his whereabouts in February 2019.

Quoting two US officials, the New York Times report said that "the US government had a role in the operation that killed the younger bin Laden, but it was not clear precisely what that role was".

NBC News was the first to report that the US has obtained intelligence about his death.
