German prosecutors say they have charged a former member of the Iraqi government's security forces with war crimes.
Federal prosecutors said on August 29 that the man, identified as 27-year-old Rami K., posted a picture on social media in which he appears holding the decapitated heads of two Islamic State (IS) fighters killed in combat.
The incident occurred when he was serving in the Iraqi military during 2015, a statement said.
The suspect is being charged with taking part in humiliating and degrading treatment.
It was not clear when he arrived in Germany or if he was seeking asylum.
The IS extremist group captured large swaths of northern and western Iraq in the summer 2014.
Iraqi forces have since launched operations aimed at uprooting the militants from the areas they control.
