Yeah, I just heard that.
I still think there is something to the story. i.e. four people have been arrested.
But, they might only be very remotely connected or their status is not entirely clear yet, or even innocent. Or perhaps, as I alluded in the post you just replied to that they have valuable intelligence and it would be in the coalition's interest to not go public yet.
We have seen before how different branches of the coalition in Iraq seem to communicate and coordinate less than perfectly.
Or AFP just made it up (which I doubt), or the Iraqi official made it up.
Who knows.
Bump to my best guess at 239.
