Diplomats say that the UN nuclear watchdog agency is expected to circulate reports on Syria and Iran later in the day. The Syrian investigation was sparked by US allegations that a building destroyed last year by Israeli jets was a nearly completed nuclear reactor meant to produce plutonium. Iran is suspected of past efforts to make nuclear arms and is under UNanctions for refusing to stop uranium enrichment. The diplomats say the Iran report will reflect failed efforts by the International Atomic Energy Agency to investigate the weapons program allegations and show that enrichment continues. They say the Syria document will expand on IAEA findings of processed uranium at the bombed site. They diplomats demanded anonymity because their information was confidential.
