Authorities said Thursday the 19-year-old man, known only as Shaas Al-M in accordance with German privacy laws, is suspected of joining IS in 2013 and taking part in military exercises in and around the Syrian city of Deir al-Zour.
Prosecutors allege that he was scouting out locations for a terror attack in Berlin on behalf of IS. He has been charged with membership in a foreign terrorist organization and violating laws regulating the transportation of weapons of war.
Additionally, he was in Germany to serve as a “contact man” for other members of IS seeking to carry out attacks, authorities said. He also allegedly recruited at least one person to send back to Syria.
The suspect was supposedly among the hundreds of thousands of refugees fleeing conflict when he entered Germany in 2015.
