A German-Afghan man whose information sparked terrorism warnings across Europe in 2010 went on trial in Germany on charges that he was a member of terrorist groups.
Ahmad Wali Siddiqui told the court in the western city of Koblenz on March 19 about his past and how he immigrated to Germany as a teenager.
The 37-year-old was captured by U.S.-led NATO troops in Afghanistan in July 2010.
While in custody, Siddiqui gave details on alleged Al-Qaeda plots apparently targeting European cities.
No attacks occurred.
Prosecutors allege that Siddiqui trained with Al-Qaeda and the Islamic Movement of Uzbekistan in Pakistan near the border with Afghanistan during 2009 and 2010 with the goal of taking part in violent jihad, or holy war.
Siddiqui faces a possible 10 years in prison if convicted.
