The beheaded bodies of a Syrian activist opposed to Daesh group and his friend were found early Friday in the southern Turkish city of Sanliurfa, his group told AFP.

Ibrahim Abdul Qader, 20, and his friend Fares Hamadi "were found beheaded at the friend's house this morning," Abu Mohammad, a founder of the "Raqa Daesh Being Slaughtered Silently" group, said via the Internet.

The group, which documents abuses in areas under Daesh control in Syria, accused the jihadist organisation of the murders on its Facebook page.
