Such is the security threat going on in France at the moment, authorities are preventing French bars and restaurants from showing Euro 2016 games on big screens outside their establishments. Screens will be permitted indoors in the bars and restaurants.
The move is to try and limit the amount of people congregating outside public places as security measures tighten amidst a potential terror threat. Authorities are expecting fewer people to gather outside official fan zones with the ban. Official fan zones have added extra security measures in recent weeks including extra video surveillance and other undisclosed things.
France's junior minister for sport Thierry Braillard has said that the fan zones will be the only outdoor screens allowed:
We can't accept unorganised gatherings because police forces don't have the means to secure them. And a live screening on a terrace means gathering around a screen.
It's better to have just one very secured area than letting thousands of people without match tickets gather in disorganised fashion.
