BAGHDAD, May 6 (UPI) -- The Iraqi government disputes U.S. allegations that Iran is stoking the sectarian violence there with money, weapons and paramilitary training.

U.S. officials said they have uncovered materials from rockets fired at the fortified Green Zone in Baghdad that bear markings of Iranian weapons manufacturers but have yet to produce any concrete physical evidence, Time magazine reported.

Those allegations and lack of evidence prompted Iraqi government spokesman Ali al-Dabbagh to tell reporters at a news conference Sunday Baghdad would handle the matter itself.

"We need our own government documentation of this interference, not from the Americans, not from the media," he said.

U.S. military spokesman Rear Adm. Patrick Driscoll said Baghdad needed to take appropriate action "based on their interpretation of the facts" regarding the U.S. allegations.

"If it turns out there is hard evidence," Dabbagh said, "the government will deal with it."
