Iran's defense minister reportedly warned the U.S. that if it attacks, Tehran is ready to teach Americans a lesson that will make them "repent forever."

Defense Minister Mostafa Mohammad-Najjar, quoted Tuesday in an interview with the Algerian News Network, charged that U.S. troop presence in the region creates "crisis" and "insecurity" in the region, and called for the removal of American presence in the region.

The Islamic Republic News Agency (IRNA) carried the defense minister's remarks on its Web site.

Iran is "fully prepared to teach a lesson to possible aggressors," Mohammad-Najjar said.

Iran is ready and willing to "confront any threat" from the U.S., and its "hostile approach" toward the country's nuclear installations, he added.

"By resorting to psychological war, the U.S. attempts to exert pressure on Iran. But such methods will rather increase the problems and complications facing the American forces in the region," he said.
