There has been no official claim of responsibility for the Manchester attack from any terror group but supporters of the Islamic State of Iraq and the Levant (Isil) celebrated the bombing on social media.

Isil supporters hailed the bombing as a victory against "the crusaders" of the West. In one video an English-speaking supporter of Isil held up a home made sign with the word "Manchester" and the date of the attack.

"This is only the beginning. The lions of Islamic State of Iraq and Sham are beginning to attack all the crusaders," the masked man said in the short video.
