Police clashed with pro-Catalan independence protesters at Camp Nou stadium as Barcelona played against Real Madrid on Wednesday.
Footage shows pro-Catalan independence supporters protesting around the Camp Nou stadium in Barcelona, where police forces gathered in force to meet them. The demonstrations escalated as protesters were setting fire to rubbish containers and throwing rocks at police.
The protest has been called on by the Tsunami Democratic group, with thousands signing up to join in. Barcelona has been rocketed by pro-independence demonstrations since the imprisonment of nine Catalan leaders in mid-October.
The biggest match of the La Liga had already been postponed to a later date before due to the protest activities in the city.
