Spanish police on Saturday clashed with a group of farmers and truck drivers in Madrid as they tried to access a main road in a bid to block it, one of several protests sweeping the European Union against the bloc's environmental rules and what workers see as excessive taxes and red tape. A group representing drivers, Plataforma Nacional, and a newly created farmers' group, Plataforma 6-F, on Saturday came together to jointly demand action from Spanish and European leaders.
