US urges Iran to 'cease attacks' on Israel to break cycle of fighting

"We urge Iran to cease its attacks on Israel so that this cycle of fighting can end without further escalation," US National Security Council spokesman Sean Savett told reporters.

The Israeli military conducted air strikes against Iran on Saturday, hitting military bases and missile sites, and other systems in several regions.

"Their response was an exercise in self-defense and specifically avoided populated areas and focused solely on military targets, contrary to Iran's attack against Israel that targeted Israel's most populous city," he added.

Stressing that the United States did not participate in the operation, he said "it is our aim to accelerate diplomacy and de-escalate tensions in the Middle East region".

A senior administration official said President Joe Biden and his national security team have worked with the "Israelis over recent weeks to encourage Israel to conduct a response that was targeted and proportional with low risk of civilian harm".

"And that appears to have been precisely what transpired this evening," the official told reporters.

President Biden had encouraged Prime Minister Benjamin Netanyahu "to design a response that served to deter further attacks against Israel while reducing risks of further escalation, and that is our objective".
