A big rally takes place on the streets of Barcelona in order to protest against the trial of the Catalan independence leaders.
The trial which started last week in Madrid has been the cause of too much controversy as the 12 former-Catalan leaders are gathering a lot of support from their Catalan people.
Activists have burned tyres and blocked a number of roads and railway tracks in Catalonia.
A strike has been called by the unions of pro-independence workers and students.
