TWENTY-TWO people, including children, have been killed and 59 injured in a suspected suicide attack at Manchester Arena.
The explosion happened at 10.35pm on Monday at the end of a concert by US singer Ariana Grande.
Police said the attack was carried out by one man, who died when he detonated an improvised explosive device.
Families continue to use social media in the hunt to find missing loved ones.
Chief Constable Ian Hopkins said it was “the most horrific incident” Greater Manchester had ever faced.
The explosion occurred shortly after pop singer Ariana Grande left the stage after a sell-out gig at the 21,000-capacity arena.
Grande (23) has a strong following of teenage girls and children.
She tweeted: “Broken. from the bottom of my heart, i am so so sorry. I don’t have words.”
The prime minister will chair a meeting of the government’s emergency Cobra committee at around 9am.
Police have set up an emergency telephone number in response to the attack.
Anyone concerned about relatives should call 0161 856 9400.
