The pictures were apparently taken by police investigators and, according to British government ministry sources, leaked by USA counterparts they had been shared with.
The pictures are said to have caused fury among police and security services, with Theresa May to raise the issue with Donald Trump at the North Atlantic Treaty Organisation summit, and some intelligence sharing put on pause.
The leaks that have led to the transatlantic row included suggestions that Abedi's family had warned security officials he was risky.
There were also reports Abedi's parents were so anxious about him being radicalised in Manchester that they got him to join them in Libya and confiscated his passport.
Abedi got his passport back after telling his father he was going on a pilgrimage to Saudi Arabia, but returned to England instead.
Speaking hours before the publication of the photographs Home Secretary Amber Rudd told BBC Radio Four the us leaks were "irritating".
As more children were named among the 22 victims of Monday's massacre, Libyan authorities detained the suicide bomber's father as well as his brother and police in Britain also carried out new arrests and raids.
Trump in turn vowed to investigate, according to a White House statement to reporters, saying "leaks of sensitive information pose a grave threat to our national security".
The New York Times published detailed pictures of the crime scene, including the remains of the suspected bomb and the rucksack worn by the suicide bomber.
But in the United States, politicians were openly briefing the media on what they had been told about Abedi and his "cell of Isis-inspired terrorists".

Leaders from 29 nations, including Italy, Russia and Indonesia, were in attendance. Britain, France and Germany were represented by finance or trade officials.
"We are furious. This is completely unacceptable", a government ministry source said.
"My heart, prayers and deepest condolences are with the victims of the Manchester Attack and their loved ones", Grande wrote.
The new arrests bring to eight the total number of men being held in the probe of the attack Monday in Manchester that killed 22 people, police said.
On Wednesday, a series of raids were executed across Manchester, Wigan and Nuneaton in Warwickshire, while relatives of Abedi were detained in Libya.
Meanwhile, Greater Manchester Police Chief Constable Ian Hopkins said the publication of leaked intelligence by the New York Times had " caused much distress for families that are already suffering terribly with their loss".
A spokesman for the Deterrence Force, which acts as Libya's Government of National Accord's police, said the brother was aware of Abedi's plan and the siblings were both members of the Islamic State jihadist group.
Elders at the south Manchester mosque believed to have been frequented by Abedi insisted that his actions were wholly alien to their preaching, and pointed the finger at online radicalisation. "This is not us".
Ariana Grande has cancelled gigs at London's O2 Arena following a terrorist attack at Manchester tour date which killed 22 people. "I know everything about my brother, what he was doing there in Manchester".
