Fox News' Rick Levanthal, embedded with the 1st Marine Light Armored Reconnaissance Battalion, said there are increasing signs of the threat of a chemical attack near Baghdad. "They have seen Iraqi forces wearing chemical suits -- unloading chemical drums ... they have witnessed this," he said.

"This comes from Marine intelligence of sightings that have taken place in Iraq on more than one occasion ... we know the threat exists and they are taking it seriously," Levanthal said.
