With Britain's terrorism threat level at "critical", meaning a new attack may be imminent, police are working around the clock to try to deter another atrocity. Wednesday's Changing of the Guard at Buckingham Palace was cancelled to redeploy police officers, while all public tours and events in Parliament have been cancelled.
"I will make clear to President Trump that intelligence that is shared between our law enforcement agencies must remain secure", May said before departing for the North Atlantic Treaty Organisation summit.
A minute's silence was observed in honor of the victims at a square in central Manchester, after which crowds broke into an emotional chorus of "Don't Look Back in Anger", an old hit song by the band Oasis who are from the city.
Queen Elizabeth II, meanwhile, visited Royal Manchester Children's Hospital to talk to some of the bombing victims, their families and the medical staff treating them. "It's awful. Very wicked.to target that sort of thing".More news: Trump makes G-7 deal on trade, takes rain check on climate
Grande wrote that her concert, by bringing people from varied backgrounds into the 21,000-capacity Manchester Arena, showed the power of music to unite. She was leaving concert when the blast struck and remembers an intense ringing but was not entirely aware that she was bleeding badly from her legs.
She credited her dad's quick action in picking her up and tying off her wounds to stem the bleeding. The tragedy took the lives of 22 innocent people and injured more than 100 others.
Several arrests have been made in both Britain and Libya after the bombing, which killed 22 people and wounded 64 more. The National Health Service said 75 people had been hospitalized. However, there is no word whether they are linked to the Manchester attack. UK Home Secretary Amber Rudd yesterday condemned American officials after CBS disclosed the name of the suicide bomber, Salman Abedi, citing American sources, after authorities in the UK asked information be withheld in order to protect the investigation. Abedi's brother and father were arrested by a militia in that country after the bombing, the militia said.
According to photographs from the scene of the attack at the 21,000-capacity Manchester Arena, Abedi's device appeared to be fairly sophisticated.More news: Hannity backs off story about slain DNC staffer
The Wall Street Journal cited a family friend saying that Abedi had travelled to Libya with his father in 2011 to join the Tripoli Brigade militia as it battled the regime of Libyan dictator Moamer Kadhafi.
The family initially lived in London before moving to Manchester where they resided in the Whalley Range area, which became famous after schoolgirls Zahra and Salma Halane left home and fled to Syria in 2015. While Abedi's family was well-known in Manchester, Abedi himself did not attend many gatherings, Fadl said.
"If they told us how many people had these extreme views just across the United Kingdom we wouldn't sleep at night". Still, Fadl said he had heard Salman's father took his son's passport away over concerns about his close ties to alleged extremists and criminals.
Mohammed Shafiq, chief executive of the Ramadhan Foundation, told The Daily Telegraph Abedi was reported two years ago "because he thought he was involved in extremism and terrorism". "And he gave a good stare, a threatening stare into the imam's eyes".More news: Argentina Reach Agreement With Sevilla Over New Boss Jorge Sampaoli
In Manchester, northwest England, feelings were still raw following Abedi's attack on a concert by U, S, pop star Ariana Grande - especially so as the bomber was born in the city.
