Security increased at Champions League ties after threat

Security has been beefed up at Champions League quarterfinal matches on Tuesday and Wednesday after a communication outlet supporting the Daesh group published threats against stadiums.

European football's governing body Uefa said all four games in Paris, Madrid and London would go ahead despite the threat.

French Interior Minister Gerald Darmanin said security would be "considerably reinforced" when Paris Saint-Germain take on Barcelona in the first leg at the Parc des Princes on Wednesday.

"The police, whom I spoke to very early this morning, have considerably reinforced the security measures," the minister told reporters.

PSG coach Luis Enrique said in his pre-match news conference: "I hope it is a thing we can control and that they are just threats and that nothing will happen."

A French source close to the issue told AFP: "Daesh has threatened the Champions League quarterfinals, not specifically in France, through one of its communication outlets."

Two games are taking place this week in Madrid -- Real Madrid host Manchester City on Tuesday, while Atletico Madrid face Borussia Dortmund on Wednesday.

Pilar Alegria, speaking for the Spanish government, said more than 2,000 police would be deployed "to guarantee total security".

"We are going to have an exceptional deployment of security services, in line with the level of alert set out by the intelligence services," Francisco Martin Aguirre, the government's delegate for Madrid, said in a video message.

In London, where Arsenal take on Bayern Munich at the Emirates Stadium on Tuesday, the Metropolitan Police said it was aware of the calls to target matches.

"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," Deputy Assistant Commissioner Ade Adelekan said.

Uefa said all the matches would be played.
