Police in Barcelona have clashed with Catalan separatists who are protesting against a rally by Spain’s national police forces in the Mediterranean city.
Catalan regional police used batons to drive back a group of separatists in the city centre, stopping them from advancing towards a march by an association of Spain’s national police forces demanding higher pay.
The violent run-ins left 20 people with injuries.
Spain has been mired in a political crisis since last year, when Catalonia’s separatist politicians failed in a breakaway bid.
Polls and recent elections show that the wealthy north-eastern region’s 7.5 million residents are roughly equally divided by the secession question.
