A leading security specialist has called the leak of critical information to US media by American intelligence officials "embarrassing."
Pictures showing the remains of a backpack, as well as shrapnel and various pieces of metal, were published online by The New York Times - leaving UK intelligence chiefs outraged.
The BBC has claimed Greater Manchester Police and UK officials have stopped sharing information with the US to ensure no further leaks.
Theresa May said she would confront US President Donald Trump over the issue during their meeting at the Nato summit in Brussels.
In an interview with James Whale and Ash Gould, Will Geddes said the pictures were most likely shared as a matter of protocol, and the authorities always have the challenge of trying to keep ahead of the press.
Geddes said the fact this information was acquired from "beyond standard protocol" will lead to "very red faces in the States", because this type of leak wasn't helpful in any shape or form.
