Iran insisted Sunday it had given a complete explanation of the discovery of highly enriched uranium by UN inspectors here, and urged the UN nuclear watchdog to focus its search on a "third country". "We have nothing more to add. This contamination came on imported equipment, so it is the third party or third country that should cooperate with the IAEA," foreign ministry spokesman Hamid Reza Asefi told reporters. "Which third country, we just can't say." | A report by the head of the International Atomic Energy Agency (IAEA) released on Tuesday said agency inspectors had found more traces in Iran of highly enriched uranium that could be bomb-grade. |
