The real story
At least as much as is known, here. The story is from 2002. Jack's link is well over two years old.
As far as the lurid account of machine gunning the containers, the second I hear "witnesses say" from a story in the Middle East, I discount it, unless there is other evidence. I could probably find a "witness" in Iraq, Afghanistan, or other places who would swear up and down that U.S. troops suck the blood out of innocent victims, turn into bats, and fly away.
