The city of Manchester has responded with acts of togetherness, kindness and strength after a suspected explosion killed 19 people at a music concert.
Police have confirmed that they are treating the explosion, which occurred outside the Manchester Arena after an Ariana Grande concert, as an act of suspected terrorism, with at least 50 people also injured.
The tragedy has stunned the world and is the worst attack in the UK since the strike on the London travel network in 2005.
But, as Manchester reacts to the horror, social media has been demonstrating heartfelt acts of support in free hotel rooms, taxis and food to people who are suffering.
The concert was attended by lots of teenagers without their parents and there have been lots of examples of support from kindhearted strangers.

Prime Minister Theresa May has said in a statement: "We are working to establish the full details of what is being treated by police as an appalling terrorist attack.
"All our thoughts are with the victims and the families of those who have been affected."
