WASHINGTON - Terror experts said Al-Qaida continues to broadcast propaganda from Iraq despite the capture of six media centers in recent months.

The U.S. military shuttered six media centers and arrested 20 suspected propaganda leaders since June in an attempt to damage al-Qaida's links to Internet communication, USA Today reported Friday.

The Internet has become increasingly important to al-Qaida to spread its message, raise money and broadcast videos of its battles with the U.S. military.

Al-Qaida knows the ultimate battle is for the "hearts and minds of the ummah," the community of Muslim believers, Gordon Woo, an analyst with London-based RMS, an anti-terrorist consulting firm, told USA Today.

It took al-Qaida just six weeks to recover from the attacks on its Iraqi media centers, said Rita Katz, who monitors terror Web portals for the SITE Institute

She noted al-Qaida's recent video alleging the failure of the U.S.-led coalition's offensive in Diyala province. The video, accompanied by music, gives viewers the impression the militants are winning overall in the war in Iraq, USA Today reported.
