Security will be increased at Champions League games this week after a media outlet supporting the Islamic State group published terror threats against match venues.
A pro-IS media channel has published multiple posters calling for attacks at stadiums hosting quarter-final ties on Tuesday and Wednesday.
Uefa said it was aware of the threats but insisted games in Madrid, Paris and London would go ahead as planned.
Ministers in both France and Spain have confirmed enhanced security measures.
French Interior Minister, Gérald Darmanin, said there would be “considerably reinforced” security measures in place when PSG play Barcelona in Paris on Wednesday.
Mr Darmanin continued: “I will remind you that only 10 days ago, IS shared a picture of the Munich stadium and said action should be taken against sports venues that host football games – although all sports can be targeted. Given how important the Champions League is for football, we are of course talking to our partners.”
Two quarter-finals are due to be held in Madrid this week. Real Madrid host Manchester City on Tuesday, while Atletico Madrid take on Borussia Dortmund on Wednesday.
Pilar Alegría, Spain’s sports minister, has issued a message of “calm” ahead of the games in Madrid and said “more than 2,000 police and civil guard officers” are being deployed.
A spokesman for European football’s governing body said: “Uefa is aware of alleged terrorist threats made towards this week’s Uefa Champions League matches and is closely liaising with the authorities at the respective venues.
“All matches are planned to go ahead as scheduled with appropriate security arrangements in place.”
Metropolitan Police Deputy Assistant Commissioner Ade Adelekan said: “We’re aware of online and media reports in relation to calls to target matches across Europe and here in London.
“However, I want to reassure the public that we have a robust policing plan in place for tonight’s match and we continue to work closely alongside the club’s security team to ensure that the match passes peacefully.”
