Even since these images of an alleged chemical attack emerged out of East Ghouta, near to
the Syrian capital of Damascus on the 21st August debate has been raging over who was
responsible.
The US, UK and France all seem convinced that Assad was behind the alleged attack while
Russia has suggested that this version of events is simply a story created by the Syrian
opposition.
So far neither side has been able, or willing, to provide evidence to either the UN or the
public that anyone was responsible for the alleged attack.
However, on the 29th August UK MPs were given a dossier by the British government which
civil service sources said provided utterly compelling proof of Assad's involvement in
the alleged attack and interestingly, YouTube videos were said to make up a key part of
this dossier thought it has not been revealed exactly which ones.
On the 28th August a video was posted online by opposition activists in Darya, a town south
of Damascus, that they claim shows Assad forces loading and firing munitions that look very
similar to the ones found at the sight of alleged chemical attack in East Ghouta.
Blogger Elliot Higgins, also known as Brown Moses believes the red berets worn by the
men in the video indicate they are members of the Syrian republic guard or military police
and say that it would be unusual
for an opposition fighter to
wear a cap associated with these organisations.
Elliott doesn't know the date for which this particular video was filmed and as it has
been taken in daylight it clearly can't be linked directly to the alleged chemical attack
in Ghouta which took place around 2.30 in the morning local time.
But, if Elliott's assessments are correct what this video does tell us is that the Assad
government has the capacity at least to fire the sorts of munitions that were found at
the site in Ghouta.
Of course opposition activists aren't the only ones circulating material online that
they say supports their version of events.
One theory doing the rounds is the suggestion that DIY weapons belonging to the opposition
can also be linked to the alleged chemical attack.
This video posted by the pro-assad website Syrianfreepress.net claims to show opposition
fighters turning gas cannisters into lethal chemical weapons.
In the video opposition fighters can be seen firing the gas cannisters from a piece of
equipment known as the Hell Cannon - a relatively new DIY rocket launcher that has only been
around for a few months .
Another theory that Elliott is keen to debunk is the claim that some of the videos coming
out of East Ghouta were actually published the day before the alleged chemical attack
even took place.
And even the Russian Foreign minister Sergei Lavrov was repeating this claim as recently
as the 26th August.
The apparent evidence for this theory is that the videos are dated the 20th August on YouTube.
We realise there is a whole mass of so-called evidence out there online that claims to support
both versions of what happened in East Ghouta on the 21st August.
So if you've got an opinion on this or if you believe you have evidence that contradicts
things that we've said in this video we'd love to hear from you.
