Chilean President Gabriel Boric: South American football governing body CONMEBOL vowed to impose tough sanctions after violent clashes between Independiente and Universidad de Chile supporters forced the abandonment of their Copa Sudamericana tie in Buenos Aires.

Wednesday's second leg at Independiente's Libertadores de America stadium in Avellaneda, on the outskirts of the Argentine capital, was halted early in the second half with the score tied at 1-1 on the night and the Chilean side leading 2-1 on aggregate.

Trouble began when visiting fans hurled objects at home supporters, prompting the latter to storm the away section. Video footage showed two Chilean fans jumping from the upper tier to escape the violence, with one later undergoing surgery and remaining in critical condition, Xinhua reports.
