Imad Eddin Barakat Yarkas alias Abu Dahdah is a Syrian-born Spaniard initially sentenced to a 27-year prison term in Spain for his part in the September 11 attacks and for his membership of the banned terrorist organization al-Qaeda. However, on 16 February 2006, the Spanish Supreme Court reduced the Abu Dahdah penalty to 12 years because it considered that his participation in the conspiracy was not proven. He is thought to have been a high-ranking member of al-Qaeda's Madrid component.
