Well, I have figured this out sometime ago. But now it is a British diplomat in Southern Iraq who is saying it.

But now the cat is out of the bag. Not realising the sensitivity that Mr Straw attaches to Britain's dealings with Teheran, the unfortunate diplomat unwittingly strayed from his referendum brief and started laying into the Iranians with a gusto not seen in the British diplomatic service for decades. The Iranians, said the diplomat, were colluding with Sunni Muslim insurgent groups in southern Iraq. They were providing them with deadly terrorist technology that has been perfected by the Iranian-funded Hizbollah militia in southern Lebanon against the Israeli army. And their motivation was to deter Britain from insisting that Teheran abandon its controversial nuclear programme."It would be entirely natural that they would want to send a message 'don't mess with us'. It would not be outside the policy parameters of Teheran."

It is important to understand the full mean of these"unwanted" revelations. Iranians got caught helping Sunni insurgents. That means not only killing British"occupiers" but also blow up Iraqi and Iranian pilgrims on their way to prayer. After all, the technology once revealed is unlikely to be used exclusively against the British. And why is it covered up? Why not inform the Iranian people about their govenment's betrayal of their fellow Shia?
