The US must rule out any further strikes on Iran if it wants to resume diplomatic talks, Tehran's deputy foreign minister has told the BBC.

Majid Takht-Ravanchi says the Trump administration has told Iran through mediators it wants to return to negotiations, but had "not made their position clear" on the "very important question" of further attacks while talks are taking place.

Israel's military operation, which began in the early hours of 13 June, scuppered a sixth round of mainly indirect talks set to take place in Muscat two days later.

The US became directly involved in the conflict between Israel and Iran last weekend when it targeted three Iranian nuclear sites in a bombing raid.

Takht-Ravanchi also said Iran will "insist" on being able to enrich uranium for what it says are peaceful purposes, rejecting accusations that Iran was secretly moving towards developing a nuclear bomb.

He said Iran had been "denied access to nuclear material" for its research programme so needed "to rely on ourselves".

"The level of that can be discussed, the capacity can be discussed, but to say that you should not have enrichment, you should have zero enrichment, and if do you not agree, we will bomb you - that is the law of the jungle," the deputy foreign minister said.

Israel began its attacks, targeting nuclear and military sites as well as assassinating commanders and scientists, in Iran on 13 June, claiming Tehran was close to building a nuclear weapon.

Iran responded by attacking Israel with missiles. Hostilities continued for 12 days, during which the US dropped bombs on three of Iran's nuclear sites: Fordo, Natanz and Isfahan.

The extent of the damage caused to Iran's nuclear programme by US strikes has been unclear, and Takht-Ravanchi said he could not give an exact assessment.

Rafael Grossi, head of the International Atomic Energy Agency (IAEA), said the strikes caused severe but "not total" damage, while US President Donald Trump declared that Iran's nuclear facilities were "totally obliterated".

Grossi also said Iran had the capacity to start enriching uranium again in "a matter of months". In response, Takht-Ravanchi said he did not know if that would be the case.

Iran's relationship with the IAEA has become increasingly strained. On Wednesday, its parliament moved to suspend cooperation with the atomic watchdog, accusing the IAEA of siding with Israel and the US.

Trump has said he would "absolutely" consider bombing Iran again if intelligence found that it could enrich uranium to concerning levels.

Takht-Ravanchi said no date had been agreed upon for a possible return to talks and he did not know what would be on the agenda, after Trump suggested discussions could take place this week.

Iran's deputy foreign minister said "right now we are seeking an answer to this question: are we going to see a repetition of an act of aggression while we are engaging in dialogue?"

He said the US had to be "quite clear on this very important question" and "what they are going to offer us in order to make the necessary confidence required for such a dialogue".

Asked if Iran could consider rethinking its nuclear programme as part of any deal, possibly in return for sanctions relief and investment in the country, Takht-Ravanchi said: "Why should we agree to such a proposal?"

He reiterated that Iran's programme, including enriching uranium to 60%, was "for peaceful purposes".

Under a 2015 nuclear deal with world powers, Iran was not permitted to enrich uranium above 3.67% purity - the level required for fuel for commercial nuclear power plants - and was not allowed to carry out any enrichment at its Fordo plant for 15 years.

However, Trump abandoned the agreement in 2018 during his first term as president, saying it did too little to stop a pathway to a bomb, and reinstated US sanctions.

Iran retaliated by increasingly breaching the restrictions - particularly those relating to enrichment. It resumed enrichment at Fordo in 2021 and had amassed enough 60%-enriched uranium to potentially make nine nuclear bombs, according to the IAEA.

Pressed on European and Western leaders having a lack of trust towards Iran, Takht-Ravanchi accused some European leaders of a "ridiculous" endorsement of US and Israeli strikes.

He said those who are criticising Iran over its nuclear programme "should criticise the way that we have been treated" and criticise the US and Israel.

He added: "And if they do not have the guts to criticise America, they should keep silent, not try to justify the aggression."

Takht-Ravanchi also said Iran had received messages through mediators that the US did "not want to engage in regime change in Iran" by targeting the country's Supreme Leader Ayatollah Ali Khamenei.

Israel's Prime Minister Benjamin Netanyahu has called on Iranians to "rise for their freedom" to bring down the clerical rule of Khamenei, but, after last week's ceasefire was reached, Trump said he did not want the same.

Takht-Ravanchi insisted it would not happen and the idea was "tantamount to a futile exercise".

He said that although some Iranians "might have criticism of some actions by the government, when it comes to foreign aggression they would be united to confront it".

The deputy foreign minister said it was "not quite clear" if the ceasefire with Israel would last, but Iran would continue to observe it "as long as there is no military attack against us".

He said Iran's Arab allies in the Persian Gulf were "doing their best to try to prepare the necessary atmosphere for a dialogue". Qatar is known to have played a key role in brokering the current ceasefire.

He added: "We do not want war. We want to engage in dialogue and diplomacy, but we have to be prepared, we have to be cautious, not to be surprised again."
