Shafaq News/ Iran notified its neighbors of its attack on Israel 72 hours in advance, Foreign Minister Hossein Amirabdollahian says.

"About 72 hours prior to our operations, we informed our friends and neighbors in the region that Iran’s response against Israel was certain, legitimate, and irrevocable," Amirabdollahian says at a press conference.

Earlier today, Iran warned Israel and the United States of a much larger response if there is any retaliation for its mass drone and missile attack on Israeli territory overnight, as Israel said "the campaign is not over yet".

The threat of open warfare erupting between the arch Middle East foes and dragging in the United States has put the region on edge as Washington said America did not seek conflict with Iran but would not hesitate to protect its forces and Israel.

Iran launched the attack over an Israeli strike on its consulate in Syria on April 1 that killed top Revolutionary Guards commanders and followed months of clashes between Israel and Iran's regional allies, triggered by the war in Gaza.

However, the attack from hundreds of missiles and drones, mostly launched from inside Iran, caused only modest damage in Israel as most were shot down with the help of the U.S., Britain and Jordan.

An Air Force base in southern Israel was hit, but continued to operate as normal and a 7-year old child was seriously hurt by shrapnel. There were no other reports of serious damage.

"We intercepted, we repelled, together we shall win," Israeli Prime Minister Benjamin Netanyahu said on social media ahead of a planned 1230 GMT meeting of the war cabinet to discuss a response to the attack.

Israeli Defence Minister Yoav Gallant said despite thwarting the attack, the military campaign was not over and "we must be prepared for every scenario".

Israel's Channel 12 TV cited an unnamed Israeli official overnight as saying there would be a "significant response" to the attack.

Iranian Foreign Minister Amir Abdollahian said Tehran had informed the United States its attack on Israel would be "limited" and for self defence.

He said Israel's neighbours had also been informed of its planned strikes 72-hours in advance.

Global powers Russia, China, France and Germany as well as Arab states Egypt, Qatar and the United Arab Emirates urged restraint.

"We will do everything to stop a further escalation," German Chancellor Olaf Scholz told reporters during a visit to China. "We can only warn everyone, especially Iran, against continuing this way."

Turkey also warned Iran it did not want further tension in the region.

The Islamic Republic's mission to the United Nations said its actions were aimed at punishing "Israeli crimes", but that it now "deemed the matter concluded".

Iranian army chief of staff Major General Mohammad Bagheri warned on television that "our response will be much larger than tonight's military action if Israel retaliates against Iran" and told Washington its bases could also be attacked if it helped Israel retaliate.

U.S. President Joe Biden has pledged "ironclad" support for Israel against Iran, but did not announce any military response on Saturday night, saying instead he would coordinate a diplomatic response with other Western leaders.
