No off-site contamination from strike on Isfahan nuclear site, IAEA says

The United States had crossed one of Iran’s most serious red lines by attacking its nuclear facilities, Iranian Foreign Minister Abbas Araghchi said Sunday.

"The US crossed a very big red line by attacking Iran’s nuclear facilities," he said.

Speaking in Istanbul, Araghchi said the US bore full responsibility for the consequences of its actions and said Tehran would respond using all tools at its disposal.

“The attack on peaceful nuclear installations marks a dangerous precedent and will not go unanswered,” he said.

Araghchi criticized Washington for undermining diplomacy and giving what he called a green light to Israel’s military operations.

"They betrayed diplomacy, they betrayed negotiations...Iran has done nothing wrong, it is difficult to understand why we were attacked on a false claim."

Regarding the overnight US attacks on nuclear site, he said "the extent of damages are being investigated."

"The international community should condemn the attacks."

Tehran reserves its right under the UN Charter to defend itself and respond proportionately to acts of aggression, he added.

US President Donald Trump launched a new war by ordering strikes on Iran’s nuclear facilities, Dmitry Medvedev, deputy chairman of Russia’s Security Council said Sunday.

“Trump, who came in as a peacemaker president, has started a new war for the US,” Medvedev wrote on Telegram.

His remarks came after Trump confirmed the US had struck three major nuclear sites in Iran and warned of further attacks if Tehran rejects peace.

The widespread presence of US military bases across the region represents not a strength but a point of vulnerability, Iran’s Revolutionary Guards said Sunday in a statement following overnight American strikes on Iranian nuclear facilities.

"As we have repeatedly stated, the number, dispersion, and extent of US military bases in the region are not a point of strength, but rather have doubled their vulnerability," the Revolutionary Guards said in a Sunday statement.

Iran’s nuclear capabilities are resilient against foreign attacks, the IRGC added.

“We firmly assert that Iran’s indigenous and peaceful nuclear technology cannot be destroyed by any attack,” the statement said.

German Chancellor Friedrich Merz has called on the Islamic Republic to immediately engage in dialogue with the United States and Israel to prevent further regional escalation, the government said Sunday.

A government spokesperson said Berlin’s aim is to find a diplomatic solution to end the conflict between Iran and Israel and avoid a broader crisis.

Diplomacy remains the sole avenue to resolve the escalating conflict between Iran and its adversaries, European Commission President Ursula von der Leyen said Sunday.

“The negotiating table is the only place to end this crisis,” she said in a statement.
