MICHAEL WARE, CNN CORRESPONDENT: Well, firstly, let me say, perhaps it's easier to deny that this is a civil war, when essentially you live in the most heavily fortified place in the country within the Green Zone, which is true of both the prime minister, the national security adviser for Iraq and, of course, the top U.S. military commanders. However, for the people living on the streets, for Iraqis in their homes, if this is not civil war, or a form of it, then they do not want to see what one really looks like.

This is what we're talking about. We're talking about Sunni neighborhoods shelling Shia neighborhoods, and Shia neighborhoods shelling back.

We're having Sunni communities dig fighting positions to protect their streets. We're seeing Sunni extremists plunging car bombs into heavily-populated Shia marketplaces. We're seeing institutionalized Shia death squads in legitimate police and national police commando uniforms going in, systematically, to Sunni homes in the middle of the night and dragging them out, never to be seen again.

I mean, if this is not civil war, where there is, on average, 40 to 50 tortured, mutilated, executed bodies showing up on the capital streets each morning, where we have thousands of unaccounted for dead bodies mounting up every month, and where the list of those who have simply disappeared for the sake of the fact that they have the wrong name, a name that is either Sunni or Shia, so much so that we have people getting dual identity cards, where parents cannot send their children to school, because they have to cross a sectarian line, then, goodness, me, I don't want to see what a civil war looks like either if this isn't one.
