Iranian Foreign Minister Abbas Araghchi said on Saturday that the ceasefire between Iran and Israel is "fragile", warning that Tehran is prepared for any breach of the agreement.
Araghchi said that the attacks by Israel and the United States were "unjustified aggression", stressing that "this ceasefire is fragile, and the reason is clear -- no ceasefire with that entity (Israel) can be relied upon".
"We are fully vigilant and prepared, and will be fully ready if this ceasefire is violated," the minister said, adding that Iran foes not wish to continue the war.
Araghchi also touched upon the prospect of re-engaging in talks with Washington.
"If they abandon military ambitions and compensate for losses, we will be ready for dialogue," he said, stressing that continued negotiations "requires serious and genuine will from the other side. They must abandon the military option and move forward towards a negotiated solution".
Tehran and Washington were in dialogue over the country's nuclear programme when Israel launched its 13 June attack on the country's nuclear facilities and assassinated key military leaders. The assault sparked a 12-day war between the two sides, during which Iran said it would not continue dialogue with the US while under fire.
Washington joined the war by striking key Iranian nuclear facilities, the outcome of which has been disputed.
US President Donald Trump on Saturday insisted that the US bombing of Iranian nuclear facilities "completely destroyed" the sites after a report said that some had largely survived.
On his Truth Social platform, Trump reiterated his frequent claim that "all three nuclear sites in Iran were completely destroyed and/or OBLITERATED".
Despite Trump's claims of total success, several US media outlets have reported leaked intelligence suggesting a hazier picture.
The latest to cast doubt was an NBC News report Friday, quoting a military damage assessment that only one of the three sites was mostly destroyed.
Experts also believe that Iran was able to remove enriched uranium from the sites before the US strikes.
