A memorandum between the United States and Iran to halt the war in the Gulf could be signed as soon as Sunday, a Western source told Reuters on Friday, with Geneva emerging as the likeliest venue.

The source said language in the memorandum was still being finalised and Iran was sticking to its position that the deal must also end fighting in Lebanon, where Israel has been battling against the Iran-backed Hezbollah militia.

The aim was to finalise the wording by Saturday so the agreement could be signed by US Vice President JD Vance and Iran's Parliament Speaker Mohammed Baqer Qalibaf. No venue had been established but Geneva was emerging as the likeliest.

Trump said on Thursday he was calling off new strikes on Iran because the deal was now ready.
