Ariana Grande releases full statement on Manchester terror attack

But they were left "furious" by repeated leaks of material shared with their U.S. counterparts, which provided an awkward backdrop for Prime Minister Theresa May's meeting with U.S. President Donald Trump at the North Atlantic Treaty Organisation summit in Brussels later in the day.

"I will make clear to President Trump that intelligence that is shared between our law enforcement agencies must remain secure", she said, in reference to an escalating diplomatic row between the United Kingdom and the US.

The 23-year-old singer had just left the stage when a suspected nail bomb was detonated by a suicide bomber at the Manchester Arena on Monday, and although the star has been left shaken by the tragedy, sources say her focus is "less about her own state" and more about "how she can help" the victims.

Later further leaked intelligence including detailed crime scene information, and photographs of shrapnel, a backpack, and a battery were released by The New York Times. The National Counter Terrorism Policing body said the breach of trust caused great "damage" and "undermines our investigations".

Abedi's father, Ramadan Abedi, and brother, Hashim, are the two arrests in Libya.

Salman Abedi was particularly upset by the killing past year of a Muslim friend whose death he believed went unnoticed by "infidels" in the United Kingdom, said the relative, speaking on condition of anonymity over concerns for her own security. French Interior Minister Gerard Collomb said Abedi had "likely" been to Syria after the trip to Libya, citing information provided by British intelligence services to their counterparts in Paris. As the investigation continues, British troops have been deployed in the central government district in Westminster, armed with assault rifles. He met with European Union officials earlier in the day to discuss issues such as climate change and trade.

Two people have since been released without charge, police said, while nine remain in custody for questioning.

Manchester police continued making arrests in the investigation with the number of detentions rising to eight in the wake of the UK's worst terrorist attack since the July 2005 bombings in London. They added they've uncovered items during the raids and searches across the city that are believed to be important to the investigation.

Abedi died in Monday's blast at an Ariana Grande concert. Another 116 people were wounded, with at least 12 children suffering from significant injuries.

Grande has since suspended her remaining Europe-wide tour until June 7.

While Mr Abedi said his son had seemed "normal" when he spoke to him five days before the atrocity, Jamal Zubia, a member of the large Libyan community in Manchester, told the Times the parents were so concerned about their son's apparent descent into extremism that they took his passport.

A Greater Manchester Police (GMP) spokeswoman did not comment to CNN on the New York Times' photo publication.
