Iran is slowing down the expansion of its enrichment capabilities at its nuclear facilities at Natanz, International Atomic Energy Agency (IAEA) Director General Mohamed ElBaradei said Monday. Speaking to journalists after a meeting discussing North Korea, the head of the UN nuclear watchdog said his inspectors saw a "fairly marked slowdown" in the process of commissioning new centrifuge cascades and the introduction of nuclear material into the cascades for enrichment. ElBaradei welcomed this development, happening at a "delicate phase" in the negotiations to end the stalemate over Iran's nuclear programme. There was no need for Iran to expand its activities at this point, he was quoted as saying by DPA news agency.
