A violent incident occurred during a Copa Sudamericana match between Argentine club Independiente and Chilean club Universidad de Chile in Avellaneda, Argentina. The match was canceled by Conmebol following clashes between the fans of both teams. Reports indicate that 19 people were injured and 97 were detained initially, with all 104 detained Universidad de Chile supporters later released. The violence included a brutal attack by Independiente supporters on Universidad de Chile fans, including an Argentine stabbed while defending a friend. Videos surfaced showing Independiente fans torturing two Chilean supporters by forcing them to undress and apologize. The Independiente stadium was closed as a sanction following the incident. Conmebol is considering further penalties, including the possible elimination of both clubs from the competition. The president of Independiente denied the club's responsibility and blamed Chilean fans, while Chilean authorities and players condemned the violence and called for justice. Chilean President Gabriel Boric stated that justice must determine those responsible and did not rule out legal action. Accusations have also been made of complicity between the police and Independiente's barra brava in the attacks. Security failures were noted, with Conmebol having issued warnings to Independiente that were allegedly ignored. The incident has sparked widespread condemnation from politicians, football officials, and media in both countries.
