On the face of it yesterdays suicide bombing that struck at the heart of Syria’s government would suggest so.
Certainly the rebels are claiming so.
An attack targeting senior members of the defence establishment needed intelligence – very good intelligence, which suggests that the rebels have sympathisers inside Asad’s regime.
Because this was a suicide attack those who had planned this move would not have had to worry about accuracy – such attacks are simple and, when they are pulled off, precise with deadly effect.
So does this means that outside powers have got involved?
Well, that’s hard to say – a suicide blast can be carried out with little training, as long as the intelligence is good, it can go on to be a deadly spectacle, which is precisely the effect a terrorist organisation would be seeking to create.
Having said that, apart from Russia and China, there are also regional powers like Hezbollah and Iran, who would have a stake in any imminent collapse of the Syrian state.
Neither of those regional powers appear to be too concerned about the level of violence in Syria.
In fact, they give the impression that they believe that at this moment, the regime of Asad are coping with the crisis.
And given the increasingly desperate calls coming from the rebels, Paris, Washington and London, they may not be wrong.
