Here is a side by side of the video posted and a photo from 2005.

Please allow me to explain.

The video in question made its initial appearance on LiveLeak with the upload date January 1st. It claims to be connected to IDF strike in the recent conflict with the header "RAW (Graphic): Scene After IDF Attack In Gaza 1/1/09".

This turned out to be a very inaccurate and misleading claim.

Someone, likely a pro-Israel right-winger (judging his attitude rebutting criticism of Israel's response to Hamas/Gaza reminiscent of Little Green Footballs fan who sought to "minimize" the horror as reflected in reddit comment history), posted a detailed comment on Reddit that debunked the claim.

Here is what the debunker by the reddit username TW9zc2Fk (who has been a registered user for only a week) said:

THIS VIDEO IS MISLEADING

The video was not taken on January 1st 2009. It was not taken in a civilian market, and it was not the result of an IDF air strike.

This video is from September 23rd 2005, and was taken in the Jabalya refugee camp in the northern Gaza Strip. A Hamas pick-up truck carrying Qassam rockets detonated by mistake during a Hamas rally, leaving at least 15 killed and dozens more injured.

The pick-up truck in question is visible for a split-second at the start of the video. The section of the video showing the pick-up exploding has been edited out. The large number of Hamas personnel present, the number of injured in military uniform, the large number of civilians and Hamas flags all over the place confirm this.

Compare the video from 4:08-4:24 with this photograph taken after the blast at the rally. In the background of the video the man shown in the white top in this photo is clearly visible tending to one of the casualties. Another person is shown coming over to him and placing the distinctive purple/green striped blanket over the body laying next to him, and the wooden pole he is knelt next to is visible.

The man in the white top is visible once again in this photograph (from this CBS News article) along with the man in a yellow shirt with serious leg injuries visible at around 3:55 in the video

A side-by-side comparison of a frame from the video at ~4:08 and the aforementioned photo from the CBS News article is here.

Because I am interested in nothing but the whole truth, after I examined his claim with proofs provided, I was forced to concede the video is misleading and had to apologize for the mistake in unintentional deception of the public.

The video is very real but the header and description that claims IDF strike that maimed and killed the victims is, regretfully, totally misleading that have nothing to do with the current conflict. The correct header to reflect accuracy should be "September 23 2005 HAMAS Rally Explosion Aftermath". The video, upon closer examination, was deliberately edited to maximize propaganda by deception (split second footage of Hamas soldier on truck at the very start then cut to carnage, not providing the true context).

I should not have jumped to the conclusion. I was bamboozled.

Let everyone you know who has seen the video of the error.
