Thousands of people took to the streets of Barcelona on Friday as part of a general strike to protest the prison sentences for Catalonia's pro-independence leaders, marking the fifth straight day of protests and demonstrations.
During the strike, police officers stationed outside the National Police Headquarters can be seen being pelted with eggs, bottles and other objects and debris.
Pau, a student attending the demonstration, said he was there to protest "excessive police reactions," and added that "we're not speaking anymore about independence, we're speaking about democratic rights, it's something more than a political idea."
Spain's Supreme Court convicted nine independence leaders, including former Catalan Vice President Oriol Junqueras, for their role in the autonomous region's attempt to secede and holding an illegal independence referendum.
The convicted leaders were given prison sentences ranging from nine to 12 years, which protesters have condemned as being disproportionately harsh.
