British police have stopped sharing information on the suicide bombing in Manchester with the US, the BBC reported on Thursday, because of fears that leaks to the US media could hinder a hunt for a possible bomb-maker still at large.
The row came as police pressed a fast-paced investigation into Monday's bombing, which killed 22 people at a music venue packed with children and raised fears a further attack could be imminent. Troops have been deployed to guard key points and eight people have been arrested.
Authorities have said the 22-year-old bomber, British-born Salman Abedi, was part of a network and had recently returned from Libya, where his parents were born.
Police chiefs have made clear they are furious about the publication of confidential material in US media, including bomb site photographs in the New York Times, saying such leaks undermined relationships with trusted security allies.
"This damage is even greater when it involves unauthorised disclosure of potential evidence in the middle of a major counter-terrorism investigation," a National Counter Terrorism Policing spokesman said in a statement.
British Prime Minister Theresa May will raise the issue with US President Donald Trump when she meets him at a Nato summit in Brussels later on Thursday, a government source said.

Greater Manchester Police say two men were arrested overnight in Manchester and in the Withington area south of the city. Officers also raided a property in the city’s Moss Side neighbourhood early Thursday and carried out a controlled explosion.
Eight men have now been detained in Britain connection with Monday’s attack. Those include Abedi’s brother Ismail, his father Ramadan Abedi said. A woman was arrested late Wednesday but was later released without charge.
Anti-EU UK Independence Party (UKIP) unveils its policy pledges on Thursday, restarting an election campaign which was suspended after the suicide attack.
Britons are due to vote on June 8, with the latest polls, published before Monday's attack, showing Prime Minister Theresa May's Conservatives comfortably ahead of the main opposition Labour Party, albeit with a narrowing lead.
The two main parties will restart their national campaigns on Friday but UKIP, which was key to securing Britain's exit from the EU, said the best response to the attack was to begin as soon as possible.
