'Jumanjihadi': Islamic militants tweet their love for Robin Williams

So wide and varied was Robin Williams' appeal ISIS fighters have even Tweeted their condolences following the comedian's death.

Islamic militants were among those who took to Twitter after the 63-year-old's sudden death went public on Monday.

Immediately after learning of his death Twitter user @mujihadi4life, who goes by the name of Abdullah wrote: "#RobinWilliams is dead? Weird. Grew up watching his movies," before the self-described activist renamed Williams' hit-movie Jumanji as "Jumanjihadi".

In response to fellow ISIS militant user @Ibn_Fullan's Tweet: "Shame. I liked Jumanji," Abdullah wrote: "good movie. Loved it as a kid."

@Ibn_Fullan's account has since been deleted.

When other Twitter users expressed their disbelief that Abdullah was openly discussing his love of Williams' films, another Islamist with the Twitter handle @ShishaniOmar wrote: "We are humans like you, joke about girls... why we shouldn't see movie? [Sic]"

The exchange saw the Islamist fighters enter into a debate about movies, with Abdullah answering a number of questions on his all-time favourite films.

"So, looks like all you have to do it support #IS and like movies to make the news," Abdullah later tweeted.

But Abdullah's mind quickly changed after fellow Islamic militants posted video of Williams mocking jihadists during a stand-up performance.

"Those that say ‘RIP’ to #RobinWilliams check out what he had to say about Islam ... May Allah make him burn," he wrote in Tweet sharing the clip.
