May, who arrived at the scene of last night's attack which also left 59 injured, said that "this attack stands out for its appalling, sickening cowardice - deliberately targeting innocent, defenceless children and young people who should have been enjoying one of the most memorable nights of their lives".
"It is now beyond doubt that the people of Manchester and of this country have fallen victim to a callous terrorist attack. It is the worst attack Manchester has suffered, and the worst to hit the north of England," Maysaid.
The attack at Manchester Arena - Europe's largest indoor arena - during the concert of Ariana Grande was claimed by the Islamic State group today.
The British prime minister, who had made her statement at the steps of Downing Street in London soon after chairing an emergency response meeting of ministers and intelligence officials of the Cabinet Office Briefing Room (Cobra), confirmed that the identity of the attacker is now known to the police but will not be released while investigations are ongoing.

"The independent Joint Terrorism Analysis Centre, which sets the threat level on the basis of the intelligence available to them, will continue to assess this throughout today and in the days ahead," she said.
She added: "We struggle to comprehend the warped and twisted mind that sees a room packed with young children not as a scene to cherish, but as an opportunity for carnage.
She praised police and security services, who acted in accordance with the plans they have in place and the exercises they conduct to test those plans.
"The cowardice of the attacker met the bravery of the emergency services and the people of Manchester. The attempt to divide us met countless acts of kindness that brought people closer together," she said.
Reiterating that campaigning for the June 8 general election campaign stands suspended, she confirmed that she will be chairing a second Cobra meeting later in the day.
