At least 22 people including several teenagers have been confirmed dead after Monday nights's explosion at a concert at the Manchester Arena in the UK, in what police are calling a terrorist attack.
US singer Ariana Grande had finished her performance at the venue when explosions were heard.
Police said the bomber, who died in the explosion, detonated the device shortly after the end of the show.
Prime Minister Theresa May said the incident was being treated as a terrorist attack.
UK correspondent, Peter Anderson has been following developments on the story.
Theresa May coincidentally talking about this as showing the worst of humanity, and describing the killer as having a warped and twisted mind.— Peter Anderson, UK correspondent
We do know that the 22 who died and the 59 currently injured were affected after the bomb went off in a foyer at the Manchester Arena.— Peter Anderson, UK correspondent
One of the focuses that the police have to be looking at at this stage is was there somebody who was aiming to cause this carnage on their own as the sole operator or were they supported in the planning and preparation, if not the carrying out of it.— Peter Anderson, UK correspondent
Anderson says police have cordoned the area and asked the public to avoid the city centre.
Meanwhile Grande has taken to Twitter to share her condolences.
