Security is of paramount importance for French authorities ahead of Euro 2016.
The murders in Paris, including the attack on the Stade de France, have led authorities to rethink plans and boost the budget.
From an initial estimate of €12m costs have doubled.
Fan zones will be of particular concern. Anne Hidalgo is the mayor of Paris: ''The fan zones will be entirely sealed off with barriers. Entrances and exits will be completely secured with tight controls, double security checks. The protocol outside large stadiums, in particular the Stade de France is as follows fans will be frisked, controlled, go through security gates. There'll also be sniffer dogs."
