While the Islamic State (formerly known as Isis) continues to expand its "Caliphate" in Syria and Iraq, several of its jihadis have taken time from supporting the religious genocide on Christians and Yazidis to discuss the death of Hollywood actor and comedian Robin Williams.

"#RobinWilliams is dead? Weird. Grew up watching his movies," tweeted one supporter of the Islamic State.

The same user, whose Twitter bio states that he is "loyal to the Caliphate", replied to another user's tweet, which read: "Shame. I liked Jumanji," with "good movie. Loved it as a kid." The original user replied: "Same, I had it on video Lol."

However, the praise for Williams' movies was short-lived. The user later tweeted: "so weird to see the kuffar [disbelievers] be so overwhelmed at the death of one person. I mean...good movies. Still a kafir [disbeliever]."

Another user who tweets "mainly about Iraq and the Levant", the areas which the Islamic State is seeking to control, tweeted a video of one of Williams' sketches as part of his 2002 comedy special 'Robin Williams: Live on Broadway' where he pokes fun at jihad in the aftermath of 9/11.

Another user, with the Islamic State flag as his Twitter picture, replied: "He committed suicide, cross dressed for a living and defames our religion may Allah give him what he deserves in the akhira [afterlife]."

Other users lambasted Williams for his support of US troops in the Afghanistan War.

It seems that, while most of social media mourned the loss of the eccentric comedian and actor, some others were intent on celebrating his death.

The actor, 63, was found dead at his home in California in an apparent suicide. His publicist said that he was "battling severe depression".

William was famous for films such as Good Morning Vietnam, Flubber, Good Will Hunting and Mrs. Doubtfire.

All television and film is banned, under the medieval interpretation of Islamic Sharia law, in the territory controlled by the Islamic State.
