Significant differences between Iran and the United States remain to ​reach a deal aimed at ending ‌the war, a senior Iranian official told Reuters on Friday, adding that keeping ​the Strait of Hormuz open ​is "conditional on U.S. adherence to the ⁠terms of ceasefire".

The official, who spoke ​on condition of anonymity, said "no agreement ​has been reached on the details of the nuclear issues," and serious negotiations are required ​to overcome differences.

He said Tehran hoped ​that a preliminary agreement could be reached in ‌the ⁠coming days with mediator Pakistan’s efforts, with the possibility of extending the ceasefire to "create space for more talks ​on lifting ​sanctions ⁠on Iran and securing compensation for war damages".

"In exchange, Iran ​will provide assurances to the ​international ⁠community about the peaceful nature of its nuclear programme," he said, adding ⁠that ​any other "narrative about the ​ongoing talks is a misrepresentation of the situation".
