Tighter security checks have been promised at World Cup stadiums after Chile fans let off fireworks when their team sealed victory over Australia.
Brazil's organising committee spokesman Saint-Clair Milesi says it aims to make security "even more rigorous."
Milesi says the incident in Cuiaba on Friday (local time) "isn't acceptable for fans and for organizers."
Chile fans lit fireworks, sending plumes of smoke across the Arena Pantanal pitch, after Jean Beausejour scored in stoppage time of a 3-1 win.
Fifa bans fireworks and flares from stadiums and requires tournament organizers to enforce security checks to prevent fans smuggling them in.
Milesi says organisers met late Friday to discuss how "to be more rigorous in terms of searches."
