The Iranian Embassy in Seoul dismissed some recent media reports claiming that hundreds of Korean scientists are cooperation with Iran in its nuclear program, saying Tehran has developed an indigenous nuclear technology which is only aimed at peaceful purposes.\"Iran\'s nuclear technology is completely domestically made, thus no foreign experts are needed,\" the embassy said in a statement to Yonhap news agency. The statement came one day after Yonhap claimed in a report that hundreds of North Korean nuclear and missile experts have been collaborating with Iranian counterparts in more than 10 locations across the Islamic state. The Iranian mission said it \"categorically rejects such allegations,\" calling the report a \"sheer lie and blatant accusation\" against Iran. Washington and its Western allies accuse Iran of trying to develop nuclear weapons under the cover of a civilian nuclear program, while they have never presented any corroborative evidence to substantiate their allegations. Iran denies the charges and insists that its nuclear program is for peaceful purposes only. Tehran stresses that the country has always pursued a civilian path to provide power to the growing number of Iranian population, whose fossil fuel would eventually run dry. 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.
