British rocker Rod Stewart apologized on Friday after he appeared to mimic a desert execution by Islamic State militants, with critics saying it was disrespectful to victims of the group. 

Stewart, 72, appeared in a clip posted on his wife's Instagram account in which he draws his finger across the throat of a man kneeling in front of him on a sand dune. It was filmed ahead of a concert he performed in Abu Dhabi. 

Critics said the clip was reminiscent of Islamic State propaganda videos featuring the beheading of Western hostages. 

Stewart, known for his 1970s hits "Maggie May" and "Da Ya Think I'm Sexy," apologized but said his actions had been misinterpreted and that he had been recreating scenes from "Game of Thrones."

"From re-enacting The Beatles' Abbey Road crossing to spontaneously playing out Game Of Thrones, we were simply larking about pre-show," he said in a statement. 

"Understandably this has been misinterpreted and I send my deepest apologies to those who have been offended."
