US Defence Secretary Lloyd Austin says the US "intercepted multiple missiles” launched by Iran towards Israel.

“We condemn this outrageous act of aggression by Iran, and we call on Iran to halt any further attacks, including from its proxy terrorist groups,” he says in a statement

President Emmanuel Macron said that French forces had been "mobilised" in the Middle East, to show his country's commitment to Israel's security.

He also promised to organise "a conference in support of the Lebanese people and its institutions" and called on Israel to put an end to its military operations there "as soon as possible".

Japanese PM Shigeru Ishiba criticised Iran’s actions as “unacceptable”, while calling on all sides to show restraint.

“We condemn this strongly. But at the same time, we would like to cooperate [with the United States] to defuse the situation and prevent it from escalating into a full-on war," he told reporters.

Australia's PM Anthony Albanese described Iran's missile attack as a "dangerous escalation” and warned that any "further hostilities" would "put civilians at risk".

Within hours of Iran's massive ballistic missile barrage, Israel's air force has conducted more strikes against what it says are Hezbollah targets in the Lebanese capital, Beirut.

The Israel Defense Forces posted on X before the latest round of air raids to warn civilians in the area it was targeting that they needed to evacuate.

Celebrations broke out on the streets of Tehran after Iran's missile barrage against Israel.

Many people in the large crowd were holding flags of Iran and Hezbollah, and displaying the face of the former Hezbollah leader who was killed in an Israeli airstrike in Lebanon on Friday.

Some let off fireworks, according to photos.

The gathering took place outside the British embassy, the same location where a similar celebration took place after Iran's attack on Israel in April.
