The US-Iran deal has bought time, but what remains to be achieved?
Memorandum of understanding expected to open pathway for talks on most contentious issues, including nuclear programme and sanctions

Writing on social media on Sunday, US President Donald Trump stated: “This Great Deal will bring Peace and Security to the whole Region.”
Representatives for the warring countries said they would formally sign a document in Switzerland on Friday that Iran’s Supreme National Security Council described as a “memorandum of understanding”.
Although the deal does not mark a final agreement, it is expected to open a pathway for negotiations on some of the most contentious issues between the two sides, including Iran’s nuclear programme and sanctions imposed on the country.
Still, Tehran has attached preconditions to potential future talks, while Trump has warned about the possibility of renewed military strikes.
What the two sides say about the deal
The full terms of the preliminary peace deal have yet to be officially released, but both the US and Iran have offered their own accounts of its content.
