BRUSSELS • World leaders reacted warily to U.S. and Israeli strikes on Iran on Saturday that triggered worries of a broader conflict.

European leaders held emergency meetings and took measures to protect their citizens in the Middle East, with key leaders calling for a negotiated settlement between Iran and the U.S. Australia and Canada were more open in their support for the strikes, while Russia and China responded with criticism.

Britain, France and Germany called for a resumption of U.S.-Iran nuclear negotiations and condemned Iranian attacks on countries in the region. They did not directly comment on the U.S. and Israeli strikes on Iran.

British Prime Minister Keir Starmer, French President Emmanuel Macron and German Chancellor Friedrich Merz said in a statement that their countries didn’t take part in the strikes on Iran but are in close contact with the U.S., Israel and partners in the region.

The three countries have led efforts to reach a negotiated solution over Iran’s nuclear program.

“We condemn Iranian attacks on countries in the region in the strongest terms. Iran must refrain from indiscriminate military strikes. We call for a resumption of negotiations and urge the Iranian leadership to seek a negotiated solution. Ultimately, the Iranian people must be allowed to determine their future,” they said.

Russia’s Foreign Ministry called the strikes “a pre-planned and unprovoked act of armed aggression against a sovereign and independent U.N. member state.” The ministry accused Washington and Tel Aviv of “hiding behind” concerns about Iran’s nuclear program while actually pursuing regime change.

China’s government said it is “highly concerned” about the U.S. and Israeli strikes on Iran and called for an immediate halt to the military action and a return to negotiations.

“Iran’s sovereignty, security and territorial integrity should be respected,” a Chinese Foreign Ministry statement said.

Concern of ‘new, extensive’ war

It is unclear whether U.S. allies were given any advance warning of the attacks. The German government said it was only given notice Saturday morning. France’s junior defense minister said France knew something would happen, but didn’t know when.

Earlier on Saturday, French President Emmanuel Macron called for an emergency U.N. Security Council meeting in response to the strikes in Iran.

“The outbreak of war among the United States, Israel and Iran has serious consequences for peace and international security,″ Macron said earlier on Saturday.

British Prime Minister Keir Starmer chaired a meeting of the government’s emergency committee on Saturday morning.

“We do not want to see further escalation into a wider regional conflict,” a U.K. government spokesperson said.

The German government’s crisis management team also was also due to meet on Saturday.

“NATO is closely following developments in Iran and the region,” NATO spokesperson Allison Hart said.

Australian Prime Minister Anthony Albanese said his country supports the U.S. in its effort to stop Iran from obtaining an atomic bomb. He described Iran’s current leadership as a destabilizing force and noted two attacks on Australian soil that were blamed on Tehran.

Australia in August cut off diplomatic relations with Iran and expelled its ambassador after accusing it of orchestrating two antisemitic attacks in the country.

Canada too, despite recent tensions with the U.S., expressed its support for the military action.

“The Islamic Republic of Iran is the principal source of instability and terror throughout the Middle East,” Prime Minister Mark Carney said.

EU urges diplomacy

Responding to the attack, the European Union’s top diplomat Kaja Kallas called the conflict in the Middle East “perilous” and said she was working with Israeli and Arab officials to pursue a negotiated peace.

EU leaders issued a joint statement Saturday, calling for restraint and engaging in regional diplomacy in hopes of “ensuring nuclear safety.”

“We call on all parties to exercise maximum restraint, to protect civilians, and to fully respect international law,” said European Commission President Ursula von der Leyen and European Council President António Costa.

Norwegian Foreign Minister Espen Barth Eide told Norwegian broadcaster NRK that he is concerned the failure of negotiations between the U.S. and Iran meant a “new, extensive war in the Middle East” would happen.

Meanwhile, Malaysian Prime Minister Anwar Ibrahim condemned Israeli strikes on Iran and accompanying U.S. military action, warning that the escalating conflict has pushed the Middle East to the “edge of catastrophe.”

Pakistan’s Foreign Minister Ishaq Dar on Saturday condemned what he described as “unwarranted attacks” on Iran during a phone call with his Iranian counterpart Abbas Araghchi.
