VIENNA (AFP) - Outgoing IAEA chief Mohamed ElBaradei fired a parting shot at Iran here Thursday, saying efforts to verify the exclusively peaceful nature of its nuclear programme had reached a dead end, as the UN atomic watchdog considered censuring Tehran. Addressing the IAEAs 35-member board of governors at the start of a two-day meeting, ElBaradei criticised Iran for long concealing a second uranium enrichment plant in Fordo, near the holy city of Qom. Irans failure to notify the agency of the existence of the plant near Qom until September 2009 was inconsistent with its obligations, he complained. Irans late declaration of the new facility reduces confidence in the absence of other nuclear facilities under construction in Iran which have not been declared to the agency, he said. And he complained that there has been no movement for well over a year from Iran on allegations it had previously been engaged in studies on nuclear weaponisation. It is now well over a year since the agency was last able to engage Iran in discussions about these outstanding issues, he said. We have effectively reached a dead end, unless Iran engages fully with us. On the uranium deal, which ElBaradei himself masterminded, the diplomat said he was disappointed that Iran has not so far agreed to the original proposal or the alternative modalities, both of which I believe are balanced and fair and would greatly help to alleviate the concerns relating to Irans nuclear programme. Meanwhile, a top Iranian official said Thursday Iran will reduce co-operation with the IAEA to a minimum if the UN atomic watchdog passes a resolution condemning its nuclear programme. Tehrans ambassador to the body, Ali Asghar Soltanieh, told German daily Sueddeutsche Zeitung its co-operation would be reduced to the minimum we are legally obliged. A vote on a resolution against his country, which would be the first in nearly four years, would damage the currently constructive atmosphere and have long-term consequences, Soltanieh was quoted as saying.
