UPDATE: According to the commentators who are fluent in Arabic below, the video appears to be filmed in Iraq based on sound and calligraphy.
The possible inaccurate information that provide sole description is probably supplied by Zionist propagandist circulating the video to blame Hamas.
Unfortunately, carnage videos appear to be misappropriated for the purpose of deception to max up propaganda. Caveat emptor.
______________
Who is aware of the fact Israel created HAMAS? Mossad's work.
What is this video that has been recently uncovered?
Where is the context?
The uploader name "daniel" is Jewish.
The sophisticated graphic art in the background and the logo make for a high propaganda value.
The content in the video is horrific -- bound and lying victims being slaughtered by the perpetrators with assault weapons.
Video "Hamas killing Palestinians in Gaza - who Israel supposes to do peace agreements with?"
(edit: the subtitle above as originally written sounds like an Israeli wrote a strange sentence structure.)
The evil perpetrators -- the murderers and the videographer -- are most likely the Synagogue of Satan.

That is a pack of rabbid zookites, executing Palestinians in cold blood, and trying to frame Hamas while they're at it.
Reminds me of the dancing israelis.
They're fucked.

Nepos, what is sung on this video sounds Iraqi to me... definitely not Palestinian... I can't read the logo because it is a little small and I seem to need glasses... but I bet that this is an Iraqi video. It is typical iraqi vocals.
Interesting... no blood.
As to why such videos are shot..., it wouldn't be the first fake video regarding the Iraq conflict with the intention of "working" on the different factions of society... Devide and rule. Who does this best? Israel and the US. There have been so many fake tapes and stories that one has stopped talking about them... or rather bothering to post about them. Remember the fake tape about the Palestinians "celebrating" 9/11... or the whole Jessica Lynch story? Or the first guy who was beheaded in Iraq.... something Berg? The list is long...
