An accompanying description, translated by Ynet News, read: “As the new Islamic State gains traction in the Middle East, we at Dreck have decided to give in to Sharia law and cheer the stubborn Da'esh [Isis].”
The Hebrew word for stubborn literally translates as “hard-necked,'”, Ynet reported, in an apparent reference to the beheadings.
The beheading-style picture appears to have been deleted after dozens of commenters criticised it, calling it “disgusting” and “poor satire” but the black flag photo remains.
Amiri Kalman, co-founder of Dreck, told Ynet the group was “reacting to current events”.
“We reject violence in any form and that includes the videos intended to scare the world," he added.
“Therefore we also refuse to participate with this fear and refuse to become hysterical. This is satire, and our way of showing our contempt of them and their videos.”
