Fifa has opened disciplinary proceedings after racist abuse was aimed at England players during the 4-0 win over Hungary in a World Cup qualifier in Budapest. Raheem Sterling and Jude Bellingham were both targeted.

England players were also pelted with objects in the second half and a flare was thrown on the pitch by the home fans at Puskas Arena. England condemned the abuse as "completely unacceptable".

Borussia Dortmund midfielder Bellingham, 18, tweeted on Friday: "Part of the game and always will be until proper punishments are put in place by those with the power. We can't let hate win, keep smiling."

Prime Minister Boris Johnson urged Fifa "to take strong action against those responsible to ensure that this kind of disgraceful behaviour is eradicated from the game for good". Football's world governing body Fifa said disciplinary proceedings had been opened "following analysis of the match reports".

It added: "Once again, Fifa would like to state that our position remains firm and resolute in rejecting any form of racism and violence as well as any other form of discrimination or abuse. We have a very clear zero tolerance stance against such abhorrent behaviours in football."

Despite Uefa ordering Hungary to play three home games behind closed doors after supporters' discriminatory behaviour, fans were allowed in on as the game came under Fifa's jurisdiction. The Uefa ban relates to racism and other discriminatory conduct which took place during Euro 2020 in June.

While Uefa manage World Cup qualifiers involving European teams, Fifa is able to take action because it is their competition.

The game's global governing body said: "Fifa strongly rejects any form of racism and violence and has a very clear zero tolerance stance for such behaviour in football." Anti-discrimination bodies Kick It Out, Show Racism the Red Card and Fare criticised Fifa and Uefa for their handling of Hungary's existing ban.

"The question for us is why Fifa didn't act to prevent this, and why the global football system didn't work together to prevent this," Kick It Out chief executive Tony Burnett said. "All I'm hearing again thus far is excuses about who should file what paperwork and who should file permission for X, Y and Z."

Fare executive director Piara Powar said allowing fans to attend in Budapest was an example of the "system falling apart" as Uefa and Fifa try to deal with racism. Powar also confirmed that the The Fare Network - an organisation trying to fight inequality in football - would provide authorities with a report of their own from the game, including video footage.

Ged Grebby, chief executive of Show Racism the Red Card, said that England manager Gareth Southgate was right to say England should "get its own house in order" before criticising others for their behaviour following a numerous instances of racism in the game. Grebby also added that a "long-term education programme" should be put in place to help tackle racism in Hungarian football.

The Professional Footballers' Association said "loopholes" that meant the game was not behind closed doors must be addressed. The players' union said. "Global football governing bodies need to demonstrate that these behaviours will never be tolerated in our game. We demand they issue the strongest sanctions possible, such as lifetime stadium bans."

England's players were booed as they took the knee before the match at the 67,000-capacity Puskas Arena to protest against racism, with a "wall of noise" bellowing around the stadium. In the second half, Sterling was pelted with paper cups and bottles when he opened the scoring for England.

A flare was later thrown on to the pitch after Harry Maguire put the visitors 3-0 ahead. England manager Gareth Southgate had ice thrown at him by fans there.

The Hungarian Football Federation (MLSZ) said that those who disrupted the match "need to be identified and severely punished", but did not make any specific reference to discriminatory abuse.

"Fans entering the field, throwing light grenades and glasses, are being identified. The MLSZ has filed/will file a police report against them," the MLSZ said. "Any fine will be passed on to the perpetrators in civil litigation, and they can expect a two-year disqualification from sporting events at the end of the trial."

"I've heard reports of racism, which I hadn't heard during the game," he said. Everyone knows what we stand for as a team, and that's completely unacceptable. It has been reported.

“Our head of security has spoken to the players and taken their statement. We will deal with it in the right channels. The world is modernising and although some people are stuck in their ways of thinking and their prejudices, they're going to be the dinosaurs in the end because the world is changing."

Hungary's minister of foreign affairs, Peter Szijjarto, questioned English complaints about the boos in Budapest in a Facebook post that included a video of England supporters at Wembley jeering during the Italian national anthem before the Euro 2020 final.
