Iran-allied IMIS militias have abducted and killed an Iraqi teenager in Baghdad, security sources told The Baghdad Post on Friday.
The sources, who spoke on anonymity, said the body was found with traces of torture and shots in the head and chest.
Iran-backed militias have committed war crimes against Iraqi civilians, particularly Sunnis, in the battle for Mosul.
In liberated areas, they have repeatedly looted, abducted and killed Sunnis.
Human rights organizations including Amnesty International released reports that spoke of war crimes by Iraqi army and allied militias against Sunnis.
