"This is not us", he said in the interview.
A total of eight people are in custody in connection with the attack. "The priority remains to establish whether he was acting alone or as part of a network", Hopkins said.
The new pictures show torn scraps from a blue rucksack as well as screws and nuts used as shrapnel and a metal item which the newspaper suggests could have been part of the bomb's detonator.
Security forces rounded up more suspects Wednesday in the deadly Manchester concert blast and soldiers fanned out across the country to national landmarks as an on-edge Britain tried to thwart the possibility of additional attacks.
"Home Secretary says she's "confident" the leaks about Manchester attack to USA media will now end", BBC political correspondent Vicki Young said on Twitter, referring to the interior minister by the commonly used title in Britain.
The BBC today reported that Britain had stopped sharing information with USA law enforcement "because of a series of leaks thought to have come from the American intelligence community". In all, six men and one woman have been arrested.
But she will also say that more needs to be done in the fight against terrorism and that the 28 North Atlantic Treaty Organisation members are at the heart of such measures, bringing "valuable operational experience and tools" to deter attacks such as the one in Manchester, where a suicide bomber killed 22 people at a pop concert.
USA media outlets have been reporting details about the attack that British officials hadn't wanted to share yet, to help in their investigation.
In a statement released by the National Police Chiefs' Council, a spokesman for National Counter Terrorism Policing said: "We greatly value the important relationships we have with our trusted intelligence, law enforcement and security partners around the world".
The changing of the guard ceremony at Buckingham Palace was canceled Wednesday so police officers can be re-deployed, Britain's defense ministry said.
Many at the concert were young girls and teens enthralled by Grande's pop power - and those who died included an 8-year-old girl. "The issue is being raised at every relevant level by the British authorities with their US counterparts".
Abedi's father, Ramadan Abedi, was arrested in Tripoli with his brother Hashim, who Libyan security forces said was "aware of all the details" of the attack.
The senior Western official tells NPR that Salman Abedi had returned from a trip to Libya in the past several days.
- A 23-year-old man is arrested by masked police in the Chorlton area of south Manchester near where Abedi is believed to have lived.
At Manchester's Didsbury Mosque, where the Abedi family worshipped, the bombing was condemned and reports that the suspected bomber had worked there were denied.
"Historically, and almost philosophically, the USA and United Kingdom intel services follow different paths", the official said on condition of anonymity because he wasn't authorized to speak about the investigation. Police raided the house early Tuesday, neighbours reported, where at least one controlled explosion was made.
A German security official told the AP on Thursday the report was accurate, speaking on condition of anonymity because the information hadn't been cleared for public release.
