Dader Manchester acted only

manchester - The victim of the bombing in Manchester probably acted alone and was not supported by a larger terrorist network. The 22-year-old Salman Abedi had obtained the most parts for his bomb himself, according to the police's anti-terrorist unit.

It was previously thought that Abedi was part of a larger terrorist network. According to the police investigation, he had 'performed different actions and actions only in the four days before the attack. '

The attack has been claimed by Islamic State (IS), but there is doubt as to whether they are really behind.
