TEHRAN -- Iran has reviewed a US-proposed 15-point plan on ending the Middle East war, and sees it as "excessive and disconnected from the realities on the battlefield," Iran's stat-run Press TV reported Wednesday.

Iran insists the war will end only on its terms and according to its timeline, Press TV cited a senior political-security official familiar with the matter as saying.

"Iran will end the war when it decides to do so and when its conditions are met," the official said.

The official added that Iran is determined to continue defense and to deal "heavy blows to the enemies" until the fulfilment of its demands.

According to the official, Iran sees the US proposed plan, "delivered by a friendly regional intermediary," as a scheme to escalate tensions.

The official listed Iran's five conditions for ending the war: a complete end to aggression and assassinations by the United States and Israel; guaranteed mechanisms to prevent future attacks; guaranteed and clearly defined payment of war damages; stopping the war across all fronts and for all resistance groups involved in the West Asia; and recognizing Iran's sovereign right over the Strait of Hormuz.

Commenting on the US plan on Wednesday, Elias Hazrati, head of the Iranian government's information council, said, "The enemy has in fact listed its unattainable desires," according to the official news agency IRNA.

The developments came after Washington had reportedly delivered Iran a 15-point plan for a month-long ceasefire deal, via intermediaries from Pakistan.

On Feb 28, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, killing Iran's then-Supreme Leader Ali Khamenei, along with senior military commanders and civilians. Iran responded by launching waves of missile and drone strikes targeting Israel and US bases and assets in the Middle East.
