Today, diplomat Richard Colvin is striking back at government and military officials who questioned his reports on Afghan detainees.

You might recall the story unfolding over the past few weeks. Colvin said that during his posting in Afghanistan in 2006-2007, he raised concern about prisoners turned over to Afghan authorities by Canadian forces.

A Parliamentary Committee in Ottawa is looking into Colvin's claim that his warnings went unheeded. The federal government has denied those allegations - and some officials questioned Colvin's credibility.

This morning, he filed a scathing reply, including, "I am not a whistle-blower, rather I am a loyal servant of the Crown, who did his job in Afghanistan to the best of his abilities."

And he said a lot more. You can read it all here.
