Iran cuts nuclear stockpile, engages with bomb probe - IAEA

VIENNA (Reuters) - Iran has cut its most sensitive nuclear stockpile by around 80 percent under an interim pact with world powers and has begun engaging with a long-stalled IAEA investigation into suspected weapons research, the U.N. atomic watchdog said on Friday.

The findings, in a quarterly report by the International Atomic Energy Agency, are likely to be welcomed by the six powers trying to negotiate a long-term deal with Iran on ending a decade-old dispute over its nuclear programme and dispelling fears of a new war in the Middle East.
