Imad Eddin Barakat Yarkas alias Abu Dahdah (Arabic: أبو الدحداح 'Abū ad-Daḥdāh) is a Syrian-born Spaniard sentenced to a 27-year prison term in Spain for his part in the September 11 attacks and for his membership in the banned terrorist organization al-Qaeda.
However, on February 16, 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.
Some reports said that Yarkas's telephone number was found in a Hamburg apartment rented by lead hijacker Mohamed Atta, while others say he was mentioned by name in a diary seized by police in a search of an anonymous apartment,[1] or that his passport had been seized in a raid on the London home of Abu Qatada.
Dahdah was one of 11 people arrested on November 19, 2001, and charged with fundraising for Al-Qaeda operatives, and his alleged role in convincing youths to attend camps in Afghanistan, camps run by his associates Anwar Adnan Mohamed Salah and Mustafa Setmariam Nasar.
Dahdah's sentence was later reduced by the Spanish Supreme Court, which ruled that the conspiracy charges were unproven.
