5 EYEWITNESS NEWS exclusive footage brings to light new questions about unguarded explosives in Iraq.

Officials with the 101st airborne division and G.P.S. technology confirms our position on or near the southern edge of the Al Qaqaa installation back on April 18, 2003 - nine days after the fall of Baghdad.

Some 377 tons of high explosives - HMX and RDX and PETN - are now missing Al-Qaqaa, and questions have arisen about what the United States knew about the site and what it did to secure it.

On the April 2003 visit, our crews witnessed soldiers using bolt cutters to get into bunkers. Inside, they found many containers marked "explosives." At least one set of crates carried the name "Al-Qaqaa State Establishment."

Military personnel told 5 EYEWITNESS NEWS that the area visited was secured by an outside perimeter. Our crew said the area felt more like no mans land.

"At one point, there was a group of Iraqis driving around in a pickup truck. We were worried they might come near us, " said former 5 EYEWITNESS NEWS reporter Dean Staley.

Photojournalist Joe Caffrey recalls seeing Iraqis watching them as they went through the bunkers. As his crew and the troops from the 101st departed each bunker, they left them open.

"We weren't quite sure what we were looking at, but we saw so much of it and it didn't appear that this was being secured in any way," said photojournalist Joe Caffrey. "It was several miles away from where military people were staying in their tents."
