Barcelona: Barcelona will join a strike called across Catalonia on Tuesday in protest against a violent crackdown by police of an independence referendum called by pro-separatist politicians for the region on Sunday.

"FC Barcelona joins the country-wide strike called for by Table for Democracy and therefore the club will be closed tomorrow (Tuesday). None of the professional teams or the youth teams at FC Barcelona will train tomorrow." Barca said in a statement on Monday.

La Liga sides Espanyol and Girona have also decided to join the strike.

Clashes as police fired rubber bullets and forced their way into polling stations, often violently removing activists, to confiscate ballots left at least 92 people confirmed injured out of a total of 844 who needed medical attention, according to Catalan authorities.

"We strongly condemn the violence carried out by the state's security forces to impede the October 1 referendum," said a 44-strong group of organisations, including leading unions, in calling the strike.

In light of the incidents, Barca played their match against Las Palmas behind closed doors on Sunday.

Barca president Josep Maria Bartomeu said the club made the decision as a protest against the violent clashes rather than security concerns. The vast majority of Barcelona's stars, including five-time World Player of the Year Lionel Messi and Gerard Pique, who has been an outspoken defender of Catalonia's right to self-determination, wouldn't have trained with Barca in Tuesday in any case as they are on international duty with their respective nations.

Espanyol and Girona, also based in Catalonia, released statements on Monday declaring their intentions to join the general strike as well.

Meanwhile, Pep Guardiola insisted Sunday's match between Barcelona and Las Palmas should not have gone ahead at all.

The Manchester City manager also criticised the decision to play the match behind closed doors at the Nou Camp. Guardiola, who managed Barcelona for four years between 2008 and 2012 , called on Spanish prime minister Mariano Rajoy to answer questions after violent scenes broke out during Catalonia's unofficial independence referendum.

Barcelona had attempted to get their La Liga fixture with Las Palmas postponed following violent clashes in the city between pro-independence voters and Spanish police.

The request was rejected by Liga de Futbol Profesional, forcing Barcelona to announce their match would be played behind closed doors.

Guardiola said he would have been against the decision, telling Catalunya Radio and RAC1: "I wouldn't have played the Barca-Las Palmas game, not at all.

"And if it did have to be played, then not behind closed doors."

The 46-year-old Catalan, who represented Barcelona for over two decades as a player and coach, was also left shocked by the scenes of violence that were broadcast around the world.
