Uefa says Champions League matches to go ahead despite terror threat

European football's governing body Uefa have said the Champions League quarter-final ties will go ahead as scheduled amid an ISIS terror threat.

The Emirates Stadium will host the first leg of Arsenal's last-eight tie against Bayern Munich on Tuesday, while Manchester City are away at Real Madrid.

On Wednesday, Paris Saint-Germain and Barcelona face off in the French capital, while Atletico Madrid host Borussia Dortmund.

A media outlet linked to the terror group issued a threat to all four ties.

"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," a statement from Uefa said.

"All matches are planned to go ahead as scheduled with appropriate security arrangements in place."

France's interior minister Gerald Darmanin said security will be "considerably reinforced" for Wednesday's match at the Parc des Princes.

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

PSG manager Luis Enrique admitted the developments are worrying.

"Who is not worried or concerned by terrorist threats?" Luis Enrique said in his pre-match press conference.

"I hope it is a thing we can control and that they are just threats and that nothing will happen."

Spanish police forces have decided to deploy 2,000 extra officers to boost security in the capital for the two games, government spokesperson Pilar Alegria said.

She said the terrorism alert level had been raised to 4 on a scale of 5.

The players, however, have to focus on the matches assuming they will go ahead.
