U.S. military spokesman Rear Admiral Greg Smith said that in the past year, 39 al Qaeda members in Iraq responsible for producing and disseminating videos and other material to thousands of Internet Web sites had been captured or killed.
"We think the vast majority of this media network has been degraded at this point," he said, adding that the arrests had led to fewer Internet postings of al Qaeda beheadings, kidnappings and other attacks in Iraq. ...
In February, U.S. intelligence monitoring of those Web sites showed 34 new postings of videos and audio material from Iraqi networks, down from 144 postings in June 2007, Smith said. "Those responsible for the more finished product, the stuff that really grabs the attention in mosques and elsewhere, we have those people on the run," he said.
