The reaction of world leaders after US forces struck three Iranian nuclear sites on Sunday Iran time ranged from Israel lauding President Donald Trump's decision to the UN calling for de-escalation and some countries condemning the attacks.

Israel Prime Minister Benjamin Netanyahu

"Congratulations, President Trump. Your bold decision to target Iran's nuclear facilities with the awesome and righteous might of the United States will change history... History will record that President Trump acted to deny the world's most dangerous regime the world's most dangerous weapons."

Iran President Masoud Pezeshkian

Iranian President Masoud Pezeshkian condemned US strikes on nuclear sites Sunday, saying in his first response that the attack revealed Washington was "behind" Israel's military campaign in the Islamic republic.

"This aggression showed that America is the main factor behind the Zionist regime's hostile actions against the Islamic Republic of Iran," he said, according to IRNA news agency, adding that the United States acted after seeing Israel's "obvious inability".

Iran Foreign Minister Abbas Araqchi

"The United States, a permanent member of the United Nations Security Council, has committed a grave violation of the UN Charter, international law and the NPT by attacking Iran's peaceful nuclear installations. The events this morning are outrageous and will have everlasting consequences. Each and every member of the UN must be alarmed over this extremely dangerous, lawless and criminal behavior. In accordance with the UN Charter and its provisions allowing a legitimate response in self-defense, Iran reserves all options to defend its sovereignty, interest, and people."

UN Secretary-General Antonio Guterres

"I am gravely alarmed by the use of force by the United States against Iran today. This is a dangerous escalation in a region already on the edge — and a direct threat to international peace and security. There is a growing risk that this conflict could rapidly get out of control — with catastrophic consequences for civilians, the region, and the world.

I call on Member States to de-escalate and to uphold their obligations under the UN Charter and other rules of international law. At this perilous hour, it is critical to avoid a spiral of chaos. There is no military solution. The only path forward is diplomacy. The only hope is peace."

New Zealand Foreign Minister Winston Peters

“We acknowledge developments in the last 24 hours, including President Trump’s announcement of US strikes on nuclear facilities in Iran. Ongoing military action in the Middle East is extremely worrying, and it is critical further escalation is avoided. New Zealand strongly supports efforts towards diplomacy. We urge all parties to return to talks. Diplomacy will deliver a more enduring resolution than further military action."

Australia Government Spokesperson

"We have been clear that Iran’s nuclear and ballistic missile program has been a threat to international peace and security. We note the US President’s statement that now is the time for peace. The security situation in the region is highly volatile. We continue to call for de-escalation, dialogue and diplomacy."

Venezuela Foreign Minister Yvan Gil

"Venezuela condemns US military aggression against Iran and demands an immediate cessation of hostilities. The Bolivarian Republic of Venezuela firmly and categorically condemns the bombing carried out by the United States military, at the request of the State of Israel, against nuclear facilities in the Islamic Republic of Iran, including the Fordow, Natanz, and Isfahan complexes."

Mexico Foreign Ministry

"The ministry urgently calls for diplomatic dialogue for peace between the parties involved in the Middle East conflict. In keeping with our constitutional principles of foreign policy and our country's pacifist conviction, we reiterate our call to de-escalate tensions in the region. The restoration of peaceful coexistence among the states of the region is the highest priority."

Cuba President Miguel Diaz-Canel

"We strongly condemn the US bombing of Iran's nuclear facilities, which constitutes a dangerous escalation of the conflict in the Middle East. The aggression seriously violates the UN Charter and international law and plunges humanity into a crisis with irreversible consequences."
