Manchester bomber 'likely' had accomplices, United Kingdom minister says

Her dramatic statement came after 22-year-old Salman Abedi, a Briton of Libyan descent, was identified as the perpetrator behind Monday's deadly attack at a concert by teen idol Ariana Grande.

In apparent reference to the involvement of British troops in military action against it, IS said the attack had been aimed at "infidels... in response to their transgressions against the lands of the Muslims".

British counterterror police say the investigation into Monday's deadly bombing after a concert in Manchester is "making good progress", but that authorities can not say yet whether the man responsible for the attack was part of a wider group.

"Today we only know what British investigators have told us - someone of British nationality, of Libyan origin, who suddenly after a trip to Libya, then probably to Syria, becomes radicalized and decides to carry out this attack", Collomb told BFMTV, according to a Reuters translation.

Grande's Dangerous Woman tour is her third one and supports her album.

British Prime Minister Theresa May said in an address to the nation late Tuesday that authorities will do everything possible to protect the public and asked people to remain vigilant. It brings together counter-terrorism experts from the police, security services and Whitehall departments.

"When we left, down the stairs there was probably early teenagers lying on the floor covered in blood and blood on the walls where they'd been laid, so it was just horrifying", female concert-goer Alex Grayson told AFP.

The attack was the deadliest in Britain since July 7, 2005 when four suicide bombers inspired by Al-Qaeda attacked London's transport system during rush hour, killing 52 people.

The minister said she was "not surprised at all" that the attack had been claimed by the Islamic State group, but said there was no information yet to confirm the extremist organisation's active direction. There's no word from Bieber yet about whether the show will go ahead.

Islamic State's claim of responsibility echoed others the group has made for attacks in the West but with vague details that left open the possibility it was an opportunistic attempt at propaganda. The data will be welcome news for new French president Emmanuel Macron, who won the election on a pledge to help his country's struggling economy, and German Chancellor Angela Merkel who seeks a fourth term in September's election. She also visited the police headquarters and a children's hospital in Manchester.

All were believed to have been at the concert and have not been traced since the attack.

Britain's Queen Elizabeth held a moment of silence at a garden party at Buckingham Palace.

The U.N. Security Council also condemned the bombing.

May said the move will allow the police to significantly increase the number of armed officers on patrol.

In 2015, Pakistani student Abid Naseer was convicted in a United States court of conspiring with al Qaeda to blow up the Arndale shopping centre in the centre of Manchester in April 2009.
