It was all hugs and smiles earlier in Geneva, when the deal was finally made...
The elation in Geneva wasn't suprising when you consider that it's taken a decade to get to this point. For a reminder of what the crisis is all about, have a look at our Q&A.
One of the cornerstones of the deal was secret talks between the US and Iran over the past year, according to unnamed officials initially quoted by the AP news agency.
The secret talks, authorised by President Obama, took place in Oman and other locations, with four meetings occurring since the election of new Iran President Hassan Rouhani in August.
