The younger brother and father of suicide bomber who killed 22 people at a concert in Manchester have been arrested in Tripoli on suspicion of links with Isis.
Investigators worry that the leaks, which they believe to originate from the USA intelligence community, will complicate the probe into what they've described as a "network" surrounding suspected suicide bomber Salman Abedi.
Manchester's mayor Andy Burnham said he has contacted the USA ambassador to the United Kingdom over the leaks to the media from the investigation into Monday's terrorist attack.
The pictures included the remains of the suspected bomb, the rucksack worn by the suicide bomber and showed bloodstains amid the wreckage. The BBC said Manchester Police hoped to resume normal intelligence relationships soon but is now furious.
Prime Minister Theresa May is expected to raise the issue of the leaks with President Donald Trump in Brussels later.
Authorities in the United Kingdom believe Salman Abedi, the suicide bomber who killed 22 people at an Ariana Grande concert in Manchester, likely had the help of a terror network and are hunting for clues to this.More news: Richard Sherman: Sherman and Seahawks do not see eye to eye

"As it stands, six men and one woman have been arrested in conjunction with the investigation and remain in custody for questioning", a British police statement said.
Greater Manchester Police will no longer share security information about the attack and investigation.
He said the priority for detectives was to establish whether Abedi was acting alone or working as part of a wider network when he set off his device after the concert by U.S. singer Ariana Grande, killing 22 people.
British home secretary [interior minister] Amber Rudd had already made clear her annoyance after American media published the bomber's identity and details of the investigation before British officials felt ready to disclose them.
Flowers and messages of condolence are left for the victims of the Manchester Arena attack.
