The US and Iran are quietly working on additional, still-unfinished agreements that would spell out how to implement a recently signed 14-point framework, including the future of Iran’s nuclear program.

The undisclosed proposals address contentious issues such as whether Iran can continue enriching uranium. For now, no final nuclear agreement exists. Source: CNN
