United Nations Secretary-General Antonio Guterres on Sunday slammed US President Donald Trumpâs decision to order US military strikes on Iranâs nuclear facilities as a âdangerous escalation.â
âI 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 â and a direct threat to international peace and security,â he said in a statement.
âThere is a growing risk that this conflict could rapidly get out of control â with catastrophic consequences for civilians, the region, and the world,â he said.

Guterres called on member states to de-escalate and to uphold their obligations under the UN Charter and other rules of international law.
âAt 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,â he said.
Other countries began reacting Sunday with calls for diplomacy and words of caution:
New Zealand
New Zealand Foreign Minister Winston Peters urged âall parties to return to talks.â
He wouldnât tell reporters Sunday whether New Zealand supported President Trumpâs actions, saying they had only just happened.
The three-time foreign minister said the crisis is âthe most serious Iâve ever dealt withâ and that âcritical further escalation is avoided.â
âDiplomacy will deliver a more enduring resolution than further military action,â he said.
China
A flash commentary from Chinaâs government-run media asked whether the US is repeating âits Iraq mistake in Iran.â
The online piece by CGTN, the foreign-language arm of the state broadcaster, said the US strikes mark a dangerous turning point.
âHistory has repeatedly shown that military interventions in the Middle East often produce unintended consequences, including prolonged conflicts and regional destabilization,â it said, citing the American invasion of Iraq in 2003.
It said a measured, diplomatic approach that prioritizes dialogue over military confrontation offers the best hope for stability in the Middle East.
Japan
Japanâs Prime Minister Shigeru Ishiba is expected to hold a meeting with key ministers Sunday afternoon to discuss the impact from the US attack on Iranian nuclear facilities, according to Japanâs NHK television.
Japanâs largest-circulation newspaper Yomiuri is distributing an extra edition on the attack in Tokyo.
South Korea
South Koreaâs presidential office said it would hold an emergency meeting Sunday to discuss the security and economic ramifications of the US strikes and potential South Korean responses.
Australia
Australia, which shuttered its embassy in Tehran and evacuated staff Friday, continued to push for a diplomatic end to the conflict.
âWe have been clear that Iranâs nuclear and ballistic missile program has been a threat to international peace and security,â a government official said in a written statement. âWe note the US Presidentâs statement that now is the time for peace.â
âThe security situation in the region is highly volatile. We continue to call for de-escalation, dialogue and diplomacy.â
Israeli Prime Minister Benjamin Netanyahu was predictably all praises for Trumpâs decision.
âYour bold decision to target Iranâs nuclear facilities, with the awesome and righteous might of the United States, will change history,â he said in a video message directed at the American president.
Netanyahu said the US âhas done what no other country on earth could do.â
Israelâs Ambassador to the UN Danny Danon also thanked Trump for his âhistoric decision to prevent Iran from obtaining nuclear weapons. Today, President Trump proved that âNever Againâ is not just a slogan â itâs a policy.â
In Washington, Congressional Republicans â and at least one Democrat â immediately praised Trump after he announced his fateful attack order.
âWell done, President Trump,â Sen. Lindsey Graham of South Carolina posted on X. Texas Sen. John Cornyn called it a âcourageous and correct decision.â Alabama Sen. Katie Britt called the bombings âstrong and surgical.â
Oklahoma Sen. Markwayne Mullin posted: âAmerica first, always.â
The Senate Armed Services Committee chairman, Roger Wicker of Mississippi, said Trump âhas made a deliberate â and correct â decision to eliminate the existential threat posed by the Iranian regime.â
Wicker posted on X that âwe now have very serious choices ahead to provide security for our citizens and our allies.â
The quick endorsements of stepped up US involvement in Iran came after Trump had publicly mulled the strikes for days and many congressional Republicans had cautiously said they thought he would make the right decision. Senate Majority Leader John Thune said Saturday evening that âas we take action tonight to ensure a nuclear weapon remains out of reach for Iran, I stand with President Trump and pray for the American troops and personnel in harmâs way.â
Thune and House Speaker Mike Johnson, R-Louisiana, were briefed ahead of the strikes on Saturday, according to people familiar with the situation and granted anonymity to discuss it.
Johnson said in a statement that the military operations âshould serve as a clear reminder to our adversaries and allies that President Trump means what he says.â
House Intelligence Committee Chairman Rick Crawford, R-Arkansas, said he had also been in touch with the White House and âI am grateful to the US servicemembers who carried out these precise and successful strikes.â
Breaking from many of his Democratic colleagues, Sen. John Fetterman of Pennsylvania, an outspoken supporter of Israel, also praised the attacks on Iran. âAs Iâve long maintained, this was the correct move by @POTUS,â he posted. âIran is the worldâs leading sponsor of terrorism and cannot have nuclear capabilities.â
Both parties have seen splits in recent days over the prospect of striking Iran. Kentucky Rep. Thomas Massie, a Republican and a longtime opponent of US involvement in foreign wars, posted on X after Trump announced the attacks that âThis is not Constitutional.â
Many Democrats have maintained that Congress should have a say. The Senate was scheduled to vote as soon as this week on a resolution by Virginia Sen. Tim Kaine requiring congressional approval before the US declared war on Iran or took specific military action.
Connecticut Rep. Jim Himes, the top Democrat on the House intelligence panel, posted on X after Trumpâs announcement: âAccording to the Constitution we are both sworn to defend, my attention to this matter comes BEFORE bombs fall. Full stop.â
