The Manchester Arena suicide bomber who killed 22 people, including an eight-year-old girl, at an Ariana Grande concert on Monday night has been named as 22-year-old Salman Abedi.
It comes after the Islamic State terror group claimed responsibility for the bombing - the worst terrorist attack in the UK since the deaths of 56 people in the 7/7 London bombings of 2005
What we know so far:
Manchester-born Abedi is suspected of detonating a homemade explosive device packed with nuts and bolts at about 10:30pm, near the foyer of the Manchester Arena, shortly after Miss Grande, the US singer, had finished her performance.
Thousands of young fans and their families were filing out of Europe's largest indoor arena when the explosion ripped through the crowds, sparking panic. Screams rang out through the venue and victims described seeing smoke and being thrown across the floor by the blast.
Singer Grande, 23, who was led to safety, said on Twitter: "broken. from the bottom of my heart, [I] am so so sorry. [I] don't have words."
