Russia on Monday denied the United States' allegations of supplying banned weapons to Iraq, which allegedly have jeopardised the use of smart ammo against the Saddam Hussein regime in the ongoing war.

"Russia has not supplied Iraq with any equipment, including military, in violation of the sanctions regime," RIA Novosti quoted Russian Foreign Minister Igor Ivanov as saying.

"Since last October, the US has repeatedly made inquiries about possible supplies by Russia of prohibited equipment to Iraq.

"These inquiries were thoroughly checked by competent Russian departments, and replies were given.

"No facts proving America's concern have been discovered," Ivanov added.

According to a Washington Post report, Russia allegedly supplied its Kornet anti-tank missiles, night-vision devices and satellite signal jammers to Iraq.

"I state with all due responsibility that any facts of breaking the sanction regime will be considered a serious violation of Russia's criminal legislation with all ensuing consequences," Ivanov said.

"The attempts to accuse our company are probably related to the serious problems in the use of US smart weapons against Iraq," Oleg Antonov, the Director General of Aviaconversiya, which makes the jammers, was quoted as saying.

Antonov said that his company had, for the first time, displayed active jammers of satellite navigational system in 1997 at the Moscow Air Show. In the next four years, the Pentagon had bought a large number of these jammers from Russia for testing their impact on the Tomahawk cruise missiles and guided bombs.

Antonov did not rule out that Iraq could have developed these jammers independently or with the help of ex-Yugoslavian experts.

"Last year the US had already studied this issue and had come to a conclusion that our company had not supplied these jammers to Iraq and the American embassy had formally apologised," Antonov said.
