US troops arrested 13 people near Saddam Hussein's home town of Tikrit, and reckon 10 of them used to work as bodyguards for him.
The US military says they moved following a tip-off, and have described the arrests as a real boost in their attempts to find Iraq's former leader.
Death of Saddam's sons
Earlier in the week Saddam Hussein's two sons, Uday and Qusay, were killed in a gun battle with US soldiers in the town of Mosul.
Since their deaths more people are coming forward with information, perhaps because they are not as afraid of being punished for doing so.
