Iran may have cleared key base of nuclear evidence: IAEA

VIENNA (AFP) - Extensive construction activities at Iran's Parchin military base may have removed all evidence of alleged nuclear weapons research, the head of the UN atomic agency said on Monday.

"As our verification capacity has been negatively impacted by extensive activities (at Parchin), it may no longer be possible to find anything even if we are given access," Yukiya Amano of the International Atomic Energy Agency told reporters in Vienna.
