FIFA President Gianni Infantino describes match where 100 fans were arrested as ‘barbaric’ and calls for sanctions.

Argentinian and Chilean football fans have traded blame after a pitched battle in a Buenos Aires stadium involving knives, sticks and stun grenades, which left 19 people injured, three seriously.

More than 100 people were arrested over some of the worst sporting violence South America has seen in years.

Chilean President Gabriel Boric described Wednesday’s incidents as an “unacceptable lynching” of his compatriots and called for justice.

The violence flared at halftime in a Copa Sudamericana round of 16 game between Argentina’s Independiente and Universidad de Chile.
