A video purportedly showing ISIS fighters executing 200 Syrian children is actually a year-old video of the execution of soldiers captured in Syrian fighting, Lead Stories has confirmed. The London's Daily Express published a story Monday headlined: "Utterly horrifying: ISIS militants gun down hundreds of CHILDREN in most sickening video," which is suggested was a new video.

London's Daily Mail also initially reported on the video as new and with children, but the paper's online edition was revised later to say it was a mass execution of Assad soldiers captured by ISIS. The revision did not reveal it was a year-old story.

The Daily Mail and Express.co.uk did not post the video -- only screenshots. Those images, however, match up with a video posted in 2014 and still viewable via LiveLeak.com. Still, the video is disturbing and should only be viewed by those who full realize what they will see.

5. When @MailOnline reports like this, it is profiteering from #IS killings. There is nothing more to it than that - clickbait.
