Prosecutors accuse German IS suspect of Syria killings role

German prosecutors are accusing a man already convicted of membership in a terrorist organization of participating in the killing of six captives by the Islamic State group.

Federal prosecutors said Tuesday they obtained a new warrant against the 28-year-old German, identified only as Harry S. in line with privacy laws, on suspicion of murder and committing war crimes.

The suspect joined IS in Syria in 2015. The new case against him relates to the public killing of six people in a square in Palmyra in June 2015. Prosecutors say he had a pistol, led one of the captives to the execution site and prevented others from fleeing.

In July, a Hamburg court sentenced him to three years in prison for membership of a terrorist group and breaching weapons export laws.
