Scores injured in violence over Barcelona independence vote

Hundreds are reportedly injured in Barcelona after Spanish national police used force to try halt Catalonia's independence referendum. Voters have been shot at with rubber bullets and attacked with batons in the regional capital Barcelona. Dozens of polling booths have been closed, but others are defiantly staying open in a bid to resist the central government's declaration forbidding the referendum. New York Times Spain correspondent Raphael Minder explains to us what's happening.
