Spanish riot police clashed with Catalan voters in Barcelona on Sunday as the controversial referendum on breaking away from Spain began.
Spanish national police began to seize ballot boxes and voting papers from Catalan polling stations, the Interior Ministry said.
An Al Jazeera correspondent at one confrontation saw several people with bleeding faces after they were beaten by security forces. Some people who attempted to vote and fought with riot police were taken away in ambulances after being injured.
At another polling station, would-be voters chanted "we are people of peace" and "we are not afraid". Half a dozen armoured police vans and an ambulance stood ready nearby, the witness said.
