The Islamic State group has claimed responsibility for last week's slaying of two Syrian activists in Turkey.
In a video posted on Monday, it warned "apostates" that "the arm of the Islamic State will reach you, wherever you are."
Ibrahim Abdul-Qadir and Fares Hamadi were found dead in an apartment in the Turkish city of Sanliurfa on Friday. Abdul-Qader was a founding member of "Raqqa is Being Slaughtered Silently," a collective of activists who document the Islamic State group's atrocities in its de facto Syrian capital. Both men are from Raqqa.
The grim video shows Hamadi's body, with his throat slit, in a dark room. Abdul-Qadir was not shown.
The video does not make clear whether it was shot in Sanliurfa. It's unclear when the two were killed.
