After last year’s blood-chilling Nice attack, French authorities are paying extra attention to security on the Riviera: special flower pot barriers, security gates, and an unheard of police presence are on order as the Cannes Film Festival kicks off. Concrete barriers in the shape of giant flower pots – 400-strong ‘flower power’, as the media has dubbed them – have been placed all over the city to prevent an assault similar to the Nice truck attack that left over 80 people dead. In addition, barriers similar to airport security tools – in particular, 160 meters of spiked chains – have appeared in the French city.
