Off With Their Heads

I have a dull, rusty bowsaw that's just about right for these guys.

Four people have been arrested over the beheading of American Nicholas Berg, Iraq sources say.

The 26-year-old businessman's decapitated body was found 10 days ago in Baghdad.

His killing was shown around the world on the internet.

The poor quality website video showed Berg dressed in orange overalls kneeling on the floor with his hands tied back.
