Barcelona: Indefinite strike at Pompeu Fabra University

Students at the Pompeu Fabra University in Barcelona have called an indefinite strike and occupied their university as part of the campaign to free the political prisoners in Catalonia – which number over 40 now, including those who have been jailed during the protests. Many of the political prisoners are students themselves, and this action has been added to by a general strike of students the following day.
