US President Donald Trump has stated he would accept a 20-year suspension by Iran of its nuclear program, in what appears to be confirmation of a shift in position away from a demand for a total end to it.
Trump said it had to be a real 20 years. Previously he has called on Iran to permanently cease enriching uranium - a stage in making a weapon - and to be prevented from ever acquiring nuclear weapons.
However, he also mentioned that his patience with Iran was running out, with no sign of a breakthrough in talks.
Israeli and US forces began massive air strikes on Iran on 28 February. A ceasefire in place since last month meant to facilitate talks has been largely observed, despite some exchanges of fire.
Pakistan has been playing the role of mediator. Both sides appear to be far apart, having rejected each other's most recent proposals to end the war.
Iranian media reported that Tehran's proposal included an immediate end to the war on all fronts and guarantees of no further attacks on Iran. Trump indicated that a 20-year suspension of Iran's nuclear provisions would be extensive and sufficient, but stipulated that it must come with substantial assurance from Iran.
This is reportedly the first time Trump has mentioned a specific 20-year timeframe. Previously, during his administration, he withdrew from a 2015 nuclear agreement with Iran due to concerns around potential expiration of restrictions.
