British Prime Minister Theresa May will confront United States President Donald Trump over the leak of information about the Manchester Arena attack when she meets him at a NATO summit in Brussels on Thursday.
The UK government has expressed its anger after a US newspaper publishing photos apparently showing the scene of the Manchester Arena attack that left 22 dead and several others injured.
"We are furious. This is completely unacceptable. These images leaked from inside the US system will be distressing for victims, their families and the wider public. The issue is being raised at every relevant level by the British authorities with their US counterparts," The Guardian quoted a Whitehall source as saying.
The New York Times had published photos which it said were gathered by UK authorities at the scene of the Manchester Arena attack.
The photos were also consequently published in the UK media.
The details about the attack emerged in American media before being confirmed by British police.
UK Home Secretary Amber Rudd said she was irritated with the early release of information about bomber Salman Abedi by the United States and told her American counterparts that no further leaks should happen.
Manchester's mayor, Andy Burnham, also expressed his anger over the leaking of information from the investigation.
Complained to acting US Ambassador about leaks out of US & was assured they would stop. They haven't. Arrogant, wrong & disrespectful to GM. https://t.co/teHhVGwYsh— Andy Burnham (@AndyBurnhamGM) May 24, 2017
"We greatly value the important relationships we have with our trusted intelligence, law enforcement and security partners around the world," said a National Counter Terrorism Policing spokesperson.
