Tehran rejected the proposal, the officials reportedly said, because it did not address the issue of control over the Strait of Hormuz.
Regional tensions have escalated over the past two weeks after Trump announced on July 8 that the ceasefire outlined in last month’s US-Iran memorandum of understanding was no longer in effect.
Since then, the US and Iran have exchanged strikes, with Washington targeting sites inside Iran while Tehran says it has attacked US military facilities and equipment across several countries in the region.
The confrontation has disrupted shipping through the Strait of Hormuz, threatened global energy supplies and prompted intermittent airspace closures, along with growing warnings of attacks on US facilities and interests beyond the Middle East.
