Activists have poured onto the streets of Barcelona to protest against the trial of 12 former Catalan independence leaders, which started last week in Madrid.

A one-day strike has also been called by the unions of pro-independence workers and students. Activists from Omnium and the Catalan National Assembly (ANC) civil groups are planning to hold a mass march this evening.

Earlier in the day, activists burned tyres and blocked a number of highways and railway tracks in the northeastern region. According to the police, they managed to reopen major roads, while some scuffles broke out with protesters.
