PARIS: The security chief for the European Championship tells The Associated Press that France will deploy anti-drone technology that will interfere with and take control of any flying machines that violate no-fly zones over stadiums. Ziad Khoury says no-fly zones will be declared over all 10 stadiums as well as training grounds for the 24 teams at next month's tournament. He says the technology will be deployed at most of the 51 matches and will 'interfere with drones and take control of them if they are spotted.' French authorities have reportedly trained for the possibility of drones being used to disperse chemical or biological weapons over crowds. Khoury described the technology as a 'dissuasive measure that didn't exist at previous sports events.'
