UEFA have fined the Croatian and Portuguese football federations for the improper conduct of their supporters during Euro 2012 matches.

The Croatian football federation, who last week were fined 80,000 euros (£64,561) after their fans were found guilty of racially abusing Italy striker Mario Balotelli, were handed a 30,000 euros (£24,000) punishment for incidents during their match with Spain - including the display of racist banners.

Their Portuguese counterparts, meanwhile, were fined 7,000 euros (£5,600) for an attempted pitch invasion by a supporter in their quarter-final against the Czech Republic.

A UEFA statement said of Croatia's fine: "The sanction has been imposed for the setting off and throwing of fireworks and the improper conduct of supporters (display of inappropriate and racist banners) at the EURO 2012 Group C fixture against Spain in Gdansk on 18 June."

The statement continued: "The Portuguese football federation (FPF), meanwhile, has been fined 7,000 euros for the inappropriate behaviour of their supporters - attempted invasion of the field of play by a fan - at the quarter-final against the Czech Republic in Warsaw on 21 June."

Croatia were knocked out of the European Championship after finishing third in Group C while Portugal face Spain in the first semi-final on Wednesday night.

Croatia's punishment last week, which was also dished out for the setting off and throwing of fireworks, was the first for a racially-aggravated offence at a tournament which has been marred by the problem.

According to official observers, Italy striker Balotelli was subjected to monkey chants by between 300 and 500 Croatia fans during the 1-1 Group B draw in Poznan.

There were also accusations of a banana being thrown onto the pitch at the Municipal Stadium.
