Iraq's Women Prisoners

We've lost two Americans this week to al-Zarqawi's reprehensible reign of terror. At first, the news was reporting that the terrorists were demanding the release of Iraqi women prisoners. Somehow, over the next few days, news reports were talking about the two bioweapon women scientists as the only Iraqi women prisoners. I wonder if this change came from interpreting the actual demands of al-Zarqawi or not. I remember from the first Abu Ghraib days that there were rumblings about many women and children being imprisoned, and potentially being mistreated. There was no real attention paid to that at the time. Have those women gone free? Is that who Zarqawi is talking about? (not that we should give him anything he demands, of course). I'm curious about this, but I don't think I'll be getting any answers.
