Armed police provided security outside the Parc des Princes stadium in Paris as it hosted one of the quarterfinal matches of the UEFA Champions League on Tuesday and Wednesday (Apr. 9-10) after a "treat" from the Islamic State terror group recently surfaced. 

A French domestic security source close to the issue told Agence France Presse that the terror group "has threatened the Champions League quarter-finals, not specifically in France, through one of its communication outlets."

Beefing Up Security in Paris, Madrid

French Interior Minister Gerald Darmanin also told reporters that the jihadist group had threatened all of the quarterfinal matches, and not just Wednesday's match between Paris Saint-Germain (PSG) and Barcelona (Barca). 

"The police, whom I spoke to very early this morning, have considerably reinforced the security measures," he said prior to the game.

Reuters also reported that Spanish authorities have also deployed over 2,000 police officers to boost security for the games there.

European football's governing body, UEFA, further said at the time that all the matches would go ahead despite the threat.

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

France would play host to the Olympics and the Paralympics later this year.
