An Islamic radical accused of playing a key role in the Madrid train bombings was extradited from Italy to Spain on Friday. Rabei Osman Sayed Ahmed, a 35-year-old Egyptian who has been of terrorism offences in Italy, is described by Spanish investigators as one of the organizers of the 2004 bombings that killed 191 people and wounded more than 1,700 people. Ahmed was arrested in Italy in June 2004. Last week, a Milan court found him guilty of subversive association aimed at international terrorism and sentenced him to 10 years in jail. The trial in the Madrid bombings is expected to begin in February. Ahmed is one of 29 people who will stand trial.
