The Pentagon says it has no definitive answer on the missing 350 tons of high explosives in Iraq.

The International Atomic Energy Agency triggered a story potentially damaging to President Bush this week, when it said 342 metric tons of explosives disappeared from the Al-Qaqaa military base in Iraq after April, 2003, due to lax security and looting.

At a news briefing Friday, former company commander, Army Major Austin Pearson said his unit removed 250 tons of ammunition from that site and destroyed it. But he said those explosives were not under the seal of the IAEA.

A Pentagon spokesman said further study is needed.

ABC News aired a video Thursday of the Al-Qaqaa base - apparently made before the explosives vanished - showing U.S. troops breaking a seal and entering a bunker full of barrels.
