The Israeli army said on Sunday it had "other goals" in Iran and intended to continue its military offensive, AFP reports.

"We have other goals and we will continue to act until we attain them," army spokesman Effie Defrin told reporters in a televised press conference.

The Israeli military said it was checking the results of a US bombing raid on the deeply buried Iranian nuclear facility in Fordo, adding that it was "too soon" to know if enriched uranium stockpiles had been destroyed, AFP reports.

Asked whether Iran had removed enriched uranium from Fordo or if it had been buried under the rubble, army spokesman Effie Defrin told reporters: "We are constantly checking the situation. It is too soon to determine. I suppose we will know later on."

France has expressed "concern" over US air strikes on Iran's nuclear facilities and called on all parties to "exercise restraint" to avoid greater conflict.

"France has taken note with concern of the strikes carried out last night by the United States of America against three sites of Iran's nuclear programme," Foreign Minister Jean-Noel Barrot posted on X.

He said France did not take part in the planning of those strikes.

Paris, Barrot added, "urges all parties to exercise restraint to avoid any escalation that could lead to an extension of the conflict".

There was no immediate reaction from President Emmanuel Macron, who had said that France and its European partners planned to step up talks with Iran.

Iran's Islamic Revolutionary Guard Corps warned the United States on Sunday to "expect regrettable responses" to its strikes on Tehran's nuclear sites, in a statement carried by state TV, AFP reports.

Iran, it said, would "use options beyond the understanding ... of the aggressor front, and the aggressors of this land must expect regrettable responses".

The Guards also said they would continue to target Israel, which has been hit by multiple waves of missile and drone attacks since it struck Iran on June 13.

Iranian Foreign Minister Abbas Araghchi, responding to a question from a Russian outlet, said he’ll travel to Moscow to meet with President Vladimir Putin after the US struck Iranian nuclear sites, AP reports.

“We enjoy a strategic partnership and we always consult with each other and co-ordinate our positions,” he said, referring to Russia.

Iran will defend itself by all means necessary, its foreign minister said on Sunday, following the US strikes against key sites in Iran's nuclear programme.

"Iran continues to defend Iran's territory, sovereignty, security and people by all means necessary against not just US military aggression, but also the reckless and unlawful actions of the Israeli regime," said Iranian diplomatic chief Abbas Araghchi on the sidelines of a meeting of the Organisation of Islamic Cooperation (OIC) in Istanbul, AFP reports.

Iran's state-run Nour News said at least 430 people have been killed and 3500 injured in Iran since Israel began its attacks, citing the Health Ministry.

The Human Rights Activists News Agency, a US-based rights organisation that tracks Iran, gave a higher toll than Tehran and said Israeli attacks have killed 639 people there, Reuters reported.

Israeli officials said 1272 people have been injured since the beginning of the hostilities, with 14 in serious condition, according to Reuters.

“The warmongering, a lawless administration in Washington is solely and fully responsible for the dangerous consequences and far reaching implications of its act of aggression,” Foreign Minister Abbas Araghchi said in a news briefing at a conference in Turkey.

Abbas Araghchi, speaking to journalists in Istanbul, said while the “door to diplomacy” should always be open, “this is not the case right now”.

These were the first public statements from a high-ranking Iranian official since the US carried out its strikes overnight.

Iranian Foreign Minister Abbas Araghchi said the United States and Israel "decided to blow up" diplomacy when they launched strikes on his country's nuclear sites.

In a post on social media, Araghchi said Israel blew up negotiations between Tehran and Washington with its strikes on June 13, while the United States did the same to talks with European powers this week with its strikes on Sunday.

 Addressing European calls for Iran to return to negotiations, he asked how Iran could "return to something it never left".

The military escalation in the Middle East risks sparking warfare with irreversible consequences, the head of the International Committee of the Red Cross said following US strikes on Iran's nuclear sites, AFP reports.

"The intensification and spread of major military operations in the Middle East risk engulfing the region – and the world – in a war with irreversible consequences," Mirjana Spoljaric, president of the International Committee of the Red Cross, said in a statement.
