On the following day of the attack, hundreds of members of the Association of Terrorism Victims staged a protest outside the Spanish Socialist Workers' Party headquarters in Madrid, shouting slogans demanding Rodriguez Zapatero's resignation. Earlier, the association president Francisco José Alcaraz asked the government to expel the Communist Party of the Basque Homelands from all regional institutions in case they did not condemn the attack. He also stated that "civil rebellion will remain unstoppable until the terrorists and all their plans have been destroyed". The association held a bigger demonstration on January 14 in Madrid.
