The head of al-Qaeda in Spain has been sentenced to 27 years in prison by a court in Madrid.
Imad Eddin Barakat Yarkas, also known as Abu Dadah, was jailed on charges of conspiracy in the September 11 attacks and for being a leader of a terrorist group.
The ruling came at the conclusion of Europe’s biggest trial of suspected Islamic extremists.
Seventeen other men were sentenced to between six and eleven years in jail for a range of terrorism offences.
Six were acquitted on all counts.
Family members have insisted that their relatives are innocent, and lawyers of several of the defendants have said they will appeal.
For their part, prosecutors are disappointed some of the more serious charges were thrown out – they worry that sets a precedent for the Madrid train bombings trials expected next year.
Most of the accused were Syrian or Moroccan-born and were accused of associating with a terrorist group, but only three were said to have helped the September 11 plotters carry out their attacks.
The defendants also included Al Jazeera journalist Taysir Alouni, who was jailed for seven years for collaborating with terrorists.
His editor denounced the ruling as a “deviation from all the norms of international justice.”
