"These allegations are baseless and without proof. In fact, the US is horrified of the spread of Iran's spiritual influence among Muslim nations," member of the parliament's National Security and Foreign Policy Commission Safar Naeemi Raz said.
The Iranian lawmaker said the US anti-Iran allegations are not new, adding that, "The main objective of the global arrogance is to reduce Iran's control over regional developments and to increase their dominance on the Middle East equations."
The US Justice Department said on Friday that a federal grand jury has indicted two men on charges of "conspiring to send materials from the United States to Iran that could be used in the enrichment of uranium".
Despite the rules enshrined in the Non-Proliferation Treaty (NPT) entitling every member state, including Iran, to the right of uranium enrichment, Tehran is now under four rounds of UN Security Council sanctions for turning down West's calls to give up its right of uranium enrichment.
Tehran has dismissed West's demands as politically tainted and illogical, stressing that sanctions and pressures merely consolidate Iranians' national resolve to continue the path.
Political observers believe that the United States has remained at loggerheads with Iran mainly over the independent and home-grown nature of Tehran's nuclear technology, which gives the Islamic Republic the potential to turn into a world power and a role model for the other third-world countries.
