CBS said Charles Duelfer, leading the US hunt for Iraq's WMD, was travelling in a convoy on Monday between Baghdad and the international airport when a suicide bomber in a car tried to ram his convoy.
"Duelfer was travelling in the second vehicle of a four vehicle convoy," it said, adding that the suicide bomber's car "was cut off by the security guards who were following in a chase car."
"Killed two in chase car ... destroys my car. Where do they get so may people who want to kill themselves?" Duelfer said in an e-mail to CBS
