Riot police have clashed with protesters outside a football match between Barcelona and Real Madrid.
Authorities sought to keep Catalonia’s separatist movement from disrupting the game viewed by 650 million people worldwide.
The match in Barcelona’s Camp Nou stadium began without incident and was halted only briefly when some fans threw balls onto the field bearing a message for the Spanish government to open a dialogue with the separatists.
Police used rubber bullets against the protesters. About 50 people were injured as a result of the confrontation. Police arrested 9 protesters.
