THOUSANDS of Catalans are taking part in strikes after Sunday’s independence referendum violence left 900 people injured.

STRIKE: Thousands of Catalans walk out after referendum violence

Angry protestors surrounding Barcelona’s national police headquarter chanted ‘occupying force’.

Catalan union leaders calling for a general strike slammed cops after footage from Sunday showed officers beating voters and firing rubber bullets.

“An attack on democracy without precedent in recent times calls for a united response,” said Javier Pacheco, secretary general of the Catalonia of the Comisiones Obreras (CCOO).

“We have called on all sectors to take part.”

Across the Catalan capital, schools and businesses closed down, but the unions’ national bodies have refused to back the strikes.

Barcelona FC said it would take part in the walk-out, closing its La Masia training ground and Camp Nou offices for the day.
