text: The 11 September 2001 attacks in the US appeared to have dealt a hard blow to ETA, owing to the worldwide toughening of "anti-terrorist" measures (such as the freezing of bank accounts), the increase in international policy coordination, and the end of the toleration some countries had, up until then, extended to ETA. Additionally, in 2002 the Basque nationalist youth movement, Jarrai, was outlawed and the law of parties was changed outlawing Herri Batasuna, the "political arm" of ETA (although even before the change in law, Batasuna had been largely paralysed and under judicial investigation by judge Baltasar Garzón).
  With ever-increasing frequency, attempted ETA actions were frustrated by Spanish security forces.
  On 24 December 2003, in San Sebastián and in Hernani, National Police arrested two ETA members who had left dynamite in a railroad car prepared to explode in Chamartín Station in Madrid. On 1 March 2004, in a place between Alcalá de Henares and Madrid, a light truck with 536 kg of explosives was discovered by the Guardia Civil.
  ETA was initially blamed for the 2004 Madrid bombings by the outgoing government and large sections of the press. However, the group denied responsibility and Islamic fundamentalists from Morocco were eventually convicted. The judicial investigation currently states that there is no relationship between ETA and the Madrid bombings.
  2006 ceasefire declaration and subsequent discontinuation
  In the context of negotiation with the Spanish government, ETA declared what it described as a "truce" several times since its creation.
