16:45 Spain demands that Catalonia call off referendum

Spain has demanded that Catalonia's separatist government call off an independence referendum, dismissing the vote as a “farce”, as national police moved in to stop it.

“Continuing this farce makes no sense, this does not lead anywhere, they should stop it immediately,” Deputy Prime Minister Soraya Saenz de Santamaria said.

The Catalan government has “behaved in an absolutely irresponsible manner, it tried to annul law and justice in Catalonia, and with it democracy,” she added.

“I don't know in what world (Catalan president Carles) Puigdemont lives, but Spanish democracy does not work like this. We have been free from a dictatorship for a long time and of a man who told us his word in the law,” Saenz de Santamaria added, in an apparent allusion to the Franco dictatorship.

Earlier, Madrid's representative in Catalonia Enric Millo told a news conference:

“Puigdemont and his team are solely responsible for all that has happened today and for all that can happen if they do not put an end to this farce.”

16:39 Human Rights Watch have urged the Spanish government to respect the right to peaceful assembly.

Barcelona's La Liga match against Las Palmas will be played behind closed doors on Sunday after the Spanish league refused to postpone the match.

“FC Barcelona condemns the events which have taken place in many parts of Catalonia today in order to prevent its citizens exercising their democratic right to free expression,” Barcelona said in a statement.   

“Given the exceptional nature of these events, the board of directors has decided that the first-team game against Las Palmas will be played behind closed doors, following the Professional Football League's refusal to postpone the game.”

Earlier, Las Palmas announced they will wear a Spanish flag on their shirts as a show of support for a united Spain.

“We have decided to embroider on our shirt a small Spanish flag and today's date, October 1, to quietly demonstrate our hope in the future of this country, and in the good will of those who live in it, in search of the best understanding,”  Las Palmas said in a statement.

bullets and indiscriminate force” against people demonstrating “peacefully”.

Alex and Marta just voted at the Escola de Concepcio at Carrer Bruc in Barcelona.

“We came an hour ago here and they made space for us to enter. There was a feeling of euphoria inside and people clapping when you cast a vote. We saw images of the policy brutality on the internet, but we weren't afraid or angered because it was expected”

11:00 Police brutality

Dozens of people waiting outside the Ramon Llull school in Barcelona were forced to take cover after hearing shots fired by officers from the National Police.

In a video taken by Daisy Bata for The Local Spain rounds of shots can be clearly be heard.

The incident was not isolated, with reports that police were forcing their way into schools across the region.

At the Escuela Cervantes on Sant Pere Més Baix in Barcelona, crowds had begun forming outside the building since 5am.

“A lot of people were waiting around the school and they've been trying to vote since 8 am,” Marc Carrasco, 46, a voting office told The Local. “The police tried to block the roads and slowly try to move people away from the small safe part of the street they were in, they must have realised it would take the whole morning to do so, so they ended up jumping through the fence with shotguns and stuff.

“I feel shaken. We managed to open the gates so people could come in and help us, we rushed to the inside and locked ourselves in but they broke open the door and came in and took the ballot box.”

Between 20 and 30 members of the national police forced their way into a polling station at Jaume Balmes High School, north west of the city center.

Spain's central government representative in Catalonia on Sunday strongly criticised the region's police force for not closing polling stations to block an independence referendum deemed illegal by
Madrid.

“Catalan police officers were ordered to block the illegal referendum and to prevent polling stations from opening, but unfortunately this was not the case in the majority of cases. Politics has prevailed over professionalism,” Enric Millo said.

It was up to officers from Spain's national police and Guardia Civil force “to act” to seize ballot boxes and voting papers and close polling stations, he added.

“The sole objective of today's operation has been to ensure that this illegal referendum does not take place and the Spanish and Catalan people can continue to live in peace and liberty as they have these past 40 years,” Millo said.

Catalan leader Carles Puigdemont managed to vote on Sunday, despite a police crackdown on polling stations.
