A deadly knife attack at the 'Festival of Diversity' in Solingen, Germany, left three people dead and eight others injured, with the Islamic State (IS) claiming responsibility for the assault. The attacker, who reportedly shouted 'Allahu Akbar' during the incident, targeted a gathering of Christians, allegedly in retaliation for perceived injustices against Muslims. Police have arrested a 15-year-old boy and another suspect linked to the attack, with the teenager accused of failing to report the crime after conversing with the assailant shortly before the stabbings. Authorities described the attack as deliberate, focusing on victims' necks, and have not ruled out terrorism as the sole motive. German leaders have called for stricter gun laws, although Interior Minister Nancy Faeser has not officially classified the incident as a terror attack. Investigations are ongoing, with police searching for additional suspects and gathering evidence from the crime scene.
