The U.S. is increasing its use of the airwaves in its effort to find weapons of mass destruction in Iraq.
An AM radio station in Baghdad operated by the U.S. Army's Psychological Operations is stepping up its appeals for Iraq's former weapons scientists to turn themselves in.
A plea broadcast today offers leniency "in accordance with the law" for anyone who cooperates.
The broadcasts are aimed at finding people to interview. Similar appeals have been airing since April.
Constant searches throughout Iraq over the last three months have turned up none of the banned weapons, which were the main justification offered by President Bush to go to war.
The pressure is mounting on Bush to explain the failure.
