Thousands gathered for vigil in show of defiance
Thousands of people gathered in the centre of Manchester in a show of defiance yesterday evening, declaring they will not be afraid in the wake of the terror attack.
The crowd erupted into applause as the vigil began, and Lord Mayor of Manchester Eddy Newman said it was a chance to "express solidarity" with the victims.
He thanked the emergency services, prompting a rapturous response from the emotional crowd.
The square later fell silent as they remembered the lives of those who died.
Poet Tony Walsh performed a touching ode to Manchester called This Is The Place, which sparked ripples of laughter, lightening the mood as the sun beamed on the Town Hall.
He described the city as "ace", hailed its "brilliant music" and said Mancunians "make people laugh" and "welcome".
In a poignant moment he referred to the "Mancunian way to survive" and "northern grit", and said: "In the face of a challenge we always stand tall."
Members of the public wept as they laid flowers and lit candles.
Many of the 59 people hurt in the attack were treated for life-threatening injuries.
Twelve of those rushed to hospital were children.
