In a warm summer evening in late August 2024, a 26-year-old Syrian national named Issa al-Hasan carried out a mass stabbing at the ‘Festival of Diversity’ in Solingen, Germany, killing three people and injuring eight others.1 The attack took place in front of the main stage during a live performance by DJ Topic, who later revealed that security personnel had urged him to continue his set to prevent mass panic among the crowd. He kept playing for another 10–15 minutes, until the music was finally stopped. Eyewitnesses reported that al-Hasan, who had been in contact with an ISIS handler on Telegram the day before the attack, had shouted ‘Allahu Akbar’ during the assault.2 One of his victims, Ines Wallusch, a 56-year-old pharmacist, bled to death in the arms of her husband after suffering a fatal stab wound to her carotid artery.
