UPDATE: British authorities on Tuesday identified the suicide bomber who struck at a Manchester Ariana Grande concert, hours after ISIS claimed responsibility for the attack.
Salman Abedi, 22, was identified as the man who detonated the improvised explosive device, killing 22 people and injuring 59.
The Telegraph reported Tuesday that Abedi was born in Manchester and that his parents had fled Libya as refugees.

American Center for Law and Justice chief counsel Jay Sekulow said there is no reason not to support President Trump's immigration executive order after the Manchester attack.
At least 19 people were killed an 50 wounded after an explosion attack at an Ariana Grande concert in Manchester, U.K.
Sekulow asked rhetorically if "anyone wants to argue we shouldn't have an executive order restricting who's coming into the country so we know who these people are?"
"[If] anyone want[s] to argue that case tonight, I'd like to take on that argument," he said.
He said the fingerprints of radical Islamic terrorism are everywhere in Europe.
Sekulow said President Trump was correct to demand Muslim countries root out radical elements in their societies during his speech in Riyadh, Saudi Arabia.
"You have got to include the Muslim community," he said.
Sekulow said lax immigration and counter-terror policies in Europe allowed radical Islamists to "infiltrate and inculcate" European neighborhoods.
As of 3 AM GMT (10 PM ET), local authorities said they were conducting a terrorism investigation but had not yet declared the attack as a terrorist act.
