Iran's nuclear research won't increase proliferation risk - Britain

VIENNA (Reuters) - The limited nuclear enrichment research and development work Iran is permitted to engage in under a nuclear deal it concluded with major powers on Tuesday will not increase the risk that Tehran could get an atomic weapon, Britain said.

"We are confident that the restricted R&D opportunities that are available to Iran under this agreement will maintain the breakout time, which has always been our primary consideration," British Foreign Secretary Philip Hammond told reporters.
