US and Europe dismiss IAEA warning in hope of saving Iran nuclear deal

UN officials unsure whether Iran building nuclear weapons but UK, France, Germany and US push for breakthrough in talks

The US and Europe have decided to set aside a fresh warning from the director general of the UN's International Atomic Energy Agency (IAEA) that it is no longer possible to say with confidence whether Iran is seeking to build a bomb, as they press on with attempting to revive its nuclear deal with the west.

Rafael Grossi says Iran is not co-operating or providing any answers to questions his agency has posed after it found nuclear particles at four undeclared sites.
