Which of the following is NOT true about the train explosions in Madrid?

Relatives of the victims of the train bombings in Madrid have condemned as excessively lenient the verdict in the trial of those involved in the attacks in the Spanish capital in 2004. Three of those at the heart of the al-Qaeda inspired conspiracy received multiple life sentences. But nobody was convicted for masterminding the bombings and some defendants received relatively light sentences. The Spanish Prime Minister Jose Luis Rodriguez Zapatero said justice had been done. But the opposition leader Mariano Rajoy said more investigation was needed. His party’s Foreign Affairs spokesman Gustavo de Aristegui told the BBC that many questions remained unanswered. "Certain details of these atrocious attacks that we still think are unknown. We still don’t know who gave the order. We still don’t know who built those bombs and we still don’t know who was the coordinator of the cells that carried out these attacks. And I think that we need to know, we must know exactly what happened there."
