23 Basque prisoners in Soria prison cut their veins. It was an act against the dispersion and attacks that they suffered in prison. Some of them were on hunger strike with other prisoners. They provoked a big well of blood, until a police officer lost consciousness. In several places in Euskal Herria there were incidents with the police in protests by the Syrian prisoners.
