 After the bombing, the ABC newspaper reported that before the attack, ETA had reminded Rodríguez Zapatero about the 2004 Madrid train bombings as a way to pressure the Government.During the ceasefire, street violence around the Basque Country, known as kale borroka, did not stop.According to Spanish police, the decision to break the truce may have come from a more violent side of ETA, opposed to any negotiations with the Spanish government, formed by members who joined ETA after participating in the kale borroka and led by Txeroki, who was in charge of all of the organisation's commandos since 2004.
