Police have confirmed 22 people died and 59 were injured following a concert by US singer Ariana Grande. It is believed a lone attacker detonated an explosive device.
“This news is absolutely heartbreaking, especially when you consider how many children and teenagers will have been at this concert,” said Mrs Long.
“My thoughts and prayers are with the people of Manchester, particularly the bereaved and injured. My deepest thanks also go to the emergency services, who had to deal with the aftermath.
“Those behind these attacks cannot be allowed to win. They try to threaten our very way of life but in doing so, inspire people to show the best of humanity by presenting generosity and compassion. That is proof good will triumph over evil.
“As a mark of respect to those killed and injured, Alliance will also be suspending General Election campaigning activity today.”
