The head of the French Football Federation (FFF) Noel Le Graet last night admitted there were now increased worries over the safety of the event after there were three explosions - thought to be from suicide bombers - outside the Stade de France stadium as France beat Germany 2-0 in an international friendly.
Fans gathered on the pitch after the final whistle and were not evacuated until just before midnight as Police shut off numerous exits as a security measure.
Elsewhere in the capital over 120 people were killed in the deadliest attacks in Europe since the 2004 Madrid bombings.
Gunmen opened fire on people in bars and restaurants as well as the 1,500-seat Bataclan theatre where concert-goers were shot dead and taken hostage.
Speaking to French newspaper L'Equipe Noel Le Graet FFF admitted the events had ramped up security concerns ahead of Euro 2016, now just seven months away.
He said: "A lot of precautions were taken, but we can see that terrorists can strike at any moment. We were already worried about the Euros; now we worry even more. But now, my thoughts are with the families."
Sporting events across Paris and the wider Île-de-France area have been cancelled, while England's friendly with France at Wembley on Wednesday is also likely to be postponed.
The Stade de France and nine other stadiums in Paris, Bordeaux, Lille, Lens, Lyon, Marseille, Nice, Saint-Etienne and Toulouse are due to stage games at the tournament next summer.
A Uefa spokesperson said this morning:
Uefa is deeply shocked and saddened by the tragic events which occurred in Paris last night and wishes to express its support and solidarity to France and to those affected by these horrible acts.
