The Islamic State group has threatened all the Champions League quarter-final matches (Marco BERTORELLO)

Security will be "considerably reinforced" at Wednesday's Champions League match in the French capital between Paris Saint-Germain and Barcelona after a "threat" from the Islamic State group, the interior minister said.

Gerald Darmanin said the jihadist group had threatened all the quarter-final matches on Tuesday and Wednesday, not just PSG's first leg clash with Barcelona at the Parc des Princes.
