Police made arrests in the United Kingdom and Libya as the investigation into a suicide bomber who killed 22 people at a Manchester concert venue packed with children focused on tracking down a network of accomplices who authorities fear could strike again.
May will raise concerns over the leaks when she meets U.S. President Trump at a North Atlantic Treaty Organisation meeting on Thursday, the BBC reported.
Grande in her statement said she has been focused "non- stop" on the victims and that "I will think of them with everything I do for the rest of my life".
The decision to stop sharing police information with USA agencies was an extraordinary step as Britain sees the United States as its closest ally on security and intelligence. When asked about intelligence sharing between the U.S. and Israel earlier this week, Prime Minister Benjamin Netanyahu, who had Trump by his side then, said it has never been better.
Britain's official threat level was raised to "critical", the highest level, late on Tuesday, meaning an attack was expected imminently. The government said almost 1,000 soldiers were deployed Wednesday instead of police in high-profile sites in London and other locations. Twenty-three remained under close care. Police officers and army personnel had rushed to a street in Hulme after a "suspicious package" was discovered there.
Queen Elizabeth visited the Royal Manchester Children's Hospital, where some of the casualties have been treated.
A national minute's silence was to be observed at 11:00am (1000 GMT) for those killed and the dozens seriously wounded.
Abedi was named by British authorities the day after he detonated a bomb packed with nuts and screws at the Manchester Arena, killing 22 people and maiming dozens more at a concert by USA pop star Ariana Grande. The victims range from an eight-year-old schoolgirl to parents who had come to pick up their children.
Belgian security services were repeatedly accused by French authorities of failing to prevent extremists from the largely Muslim Brussels neighborhood of Molenbeek from plotting the November 2015 attacks in Paris that killed 130 people.
As the probe into the possible network continues, the father and brother of suicide bomber Salman Abedi were arrested in Libya.
Abedi's father, Ramadan Abedi, and brother, Hashim, are the two arrests in Libya.
Greater Manchester Chief Constable Ian Hopkins declined to comment on whether police had found the alleged maker of the explosive device but the BBC reported that security services thought the bomb was too sophisticated for Abedi to have built by himself.
The leak of intelligence to the U.S. media has also angered British anti-terror police chiefs.
Investigators have said they are now looking at Abedi as part of a larger terrorist network that extends outside of Britain, though his father says that his son was not a jihadist.
Both Israel and the United Kingdom are America's closest allies on intelligence; the U.S. and United Kingdom belong to a close-knit intelligence sharing alliance called the "Five Eyes" with Canada, Australia and New Zealand.
