Overview

• Clashes erupted at halftime as objects—including broken seats, masonry and a reported stun grenade—were thrown from the away section, prompting home fans to storm the upper tier and attack visiting supporters.
• Counts remain disputed, with local and Chilean officials reporting more than 100 arrests and at least 19 people hospitalized, including one fan in critical condition after a fall.
• CONMEBOL said security guarantees failed, cancelled the second leg at 1-1 (Chile led 2-1 on aggregate), and referred the incident to its disciplinary bodies for sanctions.
• FIFA’s Gianni Infantino condemned the violence, while Chile’s President Gabriel Boric denounced the attacks and deployed diplomats to assist detained and injured nationals.
• Police tactics and stadium planning drew scrutiny, including the placement of visiting fans above home supporters and reports officers held back, as multiple investigations proceed.
