Fox News (boob tube) reports that US ground forces (first Marine Expeditionary) have crossed the Tigris river and are advancing (along with Army forces advancing from around Najaf across the Euphrates river) in a "zone of action" toward Baghdad.

Update: Foxnews is reporting that due to evidence that Iraqi forces have been given orders to release chemical weapons if US forces cross the "red line" around Baghdad the US ground forces moving on Baghdad are fighting with full chem/bio gear on at all times.
