A suspect has been arrested in connection with a mass stabbing at a festival in Solingen, Germany, which left three dead and eight injured. Authorities had conducted a manhunt following the attack, which is being treated as a possible act of terrorism due to the random nature of the assault. The Islamic State later claimed responsibility for the attack, describing the assailant as a 'soldier' acting in retaliation for perceived injustices against Muslims. Two additional individuals were arrested, including a 15-year-old who may have had prior communication with the attacker. German officials, including Chancellor Olaf Scholz, condemned the incident and emphasized the need for swift justice. Evidence from the scene is being analyzed as the investigation continues.
