Iran has responded negatively to an American proposal aimed at ending the ongoing imposed war, insisting that it will only occur on Tehran's own terms and timeline, a senior political-security official told Press TV on Wednesday.

The official with knowledge of the details of the proposal, speaking exclusively to Press TV, said Iran will not allow US President Donald Trump to dictate the timing of the war's end.

"Iran will end the war when it decides to do so and when its own conditions are met," the official said, emphasizing Tehran's resolve to continue its defense and inflict "heavy blows" on the enemy until its demands are fulfilled.

According to the official, Washington has been pursuing negotiations through various diplomatic channels, putting forward proposals that Tehran views as "excessive" and disconnected from the reality of America's failure on the battlefield.

The official drew parallels with two previous rounds of negotiations held in the spring and winter of 2025, characterising them as deceptive.

In both instances, the official stressed, the United States had no genuine intention to engage in meaningful dialogue and subsequently carried out military aggression against Iran.

Tehran has therefore categorized the latest overture, which was delivered via a friendly regional intermediary, as a ploy to heighten tensions and has responded negatively.

The official outlined five specific conditions under which Iran would agree to end the war. These include:

A complete halt to "aggression and assassinations" by the enemy.

The establishment of concrete mechanisms to ensure that the war is not reimposed on the Islamic Republic.

Guaranteed and clearly defined payment of war damages and reparations.

The end of the war across all fronts and for all resistance groups involved throughout the region

Iran's exercise of sovereignty over the Strait of Hormuz is and will remain Iran's natural and legal right, and it constitutes a guarantee for the implementation of the other party's commitments, and must be recognized.

The official further noted that these stipulations are in addition to demands previously presented by Tehran during the second round of negotiations in Geneva, which took place just days before the US and Israel carried out a fresh round of aggression on February 28.
