Tehran, April 4, IRNA -- Iran on Sunday strongly denied that traces of weapons-grade uranium had been found in its nuclear sites, stressing that the report in the Reuters news agency was 'baseless and false'.

"The International Atomic Energy Agency experts have not reported any case to this effect at the end of their recent visit to Tehran," Foreign Ministry spokesman Hamid Reza Asefi told reporters during a weekly news briefing.

Reuters had quoted an unnamed Western diplomat as saying that the UN atomic watchdog had found traces of highly-enriched uranium at sites, allegedly not known to the IAEA.

Iran has already denied being involved in weapons-grade uranium enrichment, clarifying that traces of the nuclear material found by the UN inspectors last year were related to the contaminated equipment bought from abroad.

Asefi stressed that 'the Islamic Republic is committed to what it has announced so far and believes that various issues will be resolved through the agreement of the two sides'. Tehran, which is a signatory to the nuclear Non-Proliferation

Treaty, has signed to the snap inspection of its atomic facilities. The country says its nuclear program is in accordance with the country's bid to produce 7,000 megawatts of electricity in the next 20 years, when the country's oil and gas reserves become overstretched.
