The Copa Sudamericana match between Argentina's Club Atlético Independiente and Chile's Universidad de Chile, held in Buenos Aires on August 20, 2025, was suspended due to violent clashes between fans. The incidents resulted in at least 20 injuries, including 10 serious cases, and over 100 arrests. Among the injured, 19 Universidad de Chile supporters were hospitalized, with two in neurocritical care and one in critical condition. During the violence, a Universidad de Chile fan jumped from a height to escape an attack by Independiente supporters. The Chilean government, led by President Gabriel Boric, condemned the aggression and instructed Interior Minister Álvaro Elizalde to travel to Argentina to accompany the injured fans and oversee the situation of the detained. The Argentine police and Conmebol, the South American football governing body, faced criticism for inadequate security and delayed suspension of the match. Conmebol has opened disciplinary proceedings against both clubs and is considering sanctions. The Argentine judiciary ordered the release of 104 detained Chilean fans following diplomatic efforts. Allegations emerged accusing some Independiente fans and police of collusion to target Chilean supporters. Independiente released a video blaming Universidad de Chile fans for inciting violence, a claim rejected by the Chilean club. The events have prompted calls for stronger measures to combat football-related violence in South America. Separately, the Chilean football association suspended Universidad de Chile's next league match against Everton in response to the incident. President Boric has not ruled out legal action regarding the attacks on Chilean fans. The violent outbreak has drawn international attention and criticism, highlighting ongoing challenges in managing fan violence in the region.
