Pakistan has declared that a US-Iran peace deal is “expected in the next 24 hours”, as uncertainty continues over the prospect of an immediate end to the conflict.

Donald Trump said that a memorandum of understanding could be signed as soon as Sunday in Europe, while Iranian foreign minister Abbas Araghchi said the deal “has never been closer”.

However, US and Iranian officials have given conflicting accounts of the agreed terms as Shehbaz Sharif, the prime minister of Pakistan, warned against a “misinformation campaign” designed to “sabotage” reconciliation.

Trump has since expressed frustration over slow progress, describing the Iranians as “very dishonourable people to deal with” and calling on them to “get their act together, and FAST!”

Here are the major points of tension that still need to be straightened out before a deal can be reached.
