World powers say Teheran's uranium stocks still growing

VIENNA - Iran outlined to the United Nations nuclear watchdog on Monday a deal to give up some of its enriched uranium, calling it major progress toward resolving a standoff with world powers now pursuing tougher sanctions against Teheran.

A letter signed by Iranian nuclear program chief Ali Akbar Salehi was handed over to International Atomic Energy Agency director-general Yukiya Amano at a 45-minute meeting in Vienna, an Iranian diplomat told reporters. He gave no details.
