According to Western intelligence, Iraq has failed to find its own volunteers for suicide missions against coalition troops. Whitehall security sources have told the BBC they have reliable information from inside Iraq that a trawl for volunteers amongst the ruling Baath Party failed to find any takers. According to the sources, a decision was taken to use remotely-detonated bombs in vehicles without the drivers' knowledge.
They say the man who blew himself up in Najaf on Saturday killing four US Marines almost certainly did not know he was going to die.
British security sources say this shows the desperation of the Iraqi regime. There is no immediate way of verifying their claims.
