A hashtag, which translates as "ISIS crappy collage grand prix" or "photoshop grand prix", was created and users have been using it to post parodies of the hostage video.

The video released by the group on Tuesday shows a militant, dressed in black and brandishing a knife as he stands between Kenji Goto and Haruna Yukawa, who are both clad in orange jumpsuits.

This image has been photoshopped to make the British-accented jihadi a ninja and Dr Evil, while in others the two hostages appear as Japanese anime characters.
