Considering alternative plans for Euro 2016 is "playing the game of the terrorists", according to the organizing committee chairman.
Organizing committee chairman Jacques Lambert warned against considering cancelling or moving Euro 2016 in the wake of the Paris attacks.
Officials say 129 people were killed and 99 critically injured in what appeared to be coordinated strikes across the French capital on Friday, including a blast at the Stade de France.
The deaths have raised fears ahead of Euro 2016, scheduled to be hosted by France in June and July next year.
But Lambert said it was wrong to be thinking about alternative plans for the tournament.
