'Precise, powerful' hits on Iran's missile production

Israel's airstrikes "hit hard" Iran's defences and missile production, Prime Minister Benjamin Netanyahu says as Iranian Supreme Leader Ayatollah Ali Khamenei revealed the country was considering its response.

With warfare raging in Gaza and Lebanon, direct confrontation between Israel and Iran risks spiralling into a regional conflagration. But a day after the airstrikes, there was no sign they would spark another round of escalation.

However, heavy fighting in Lebanon between Israeli forces and Iran-backed Hezbollah, which sharply intensified over recent weeks, continued on Sunday with an Israeli airstrike killing eight people in a residential block in Sidon, medics said.

"The air force attacked throughout Iran. We hit hard Iran's defence capabilities and its ability to produce missiles that are aimed at us," Netanyahu said in a speech, calling the attack "precise and powerful" and saying it met all its objectives.

Israel's army chief, Lieutenant General Herzi Halevi, said the strike on Iran had showed what the Israeli response to its enemies would be. "We struck strategic systems in Iran, which carries great importance, and we will now see how things develop. We are prepared for all scenarios in every arena."

The Islamic Republic has not signalled how it will respond to Saturday's long-anticipated strikes, which involved scores of fighter jets bombing targets near the capital Tehran and in the western provinces of Ilam and Khuzestan.

The U.N. Security Council will likely convene to discuss the attack on Monday, diplomats said.

The heavily armed arch-enemies have engaged in a cycle of retaliatory moves against each other for months, with Saturday's strike coming after an Iranian missile barrage on October 1, much of which Israel said was downed by its air defences.

Khamenei said Israel's calculations "should be disrupted".

The attack on Iran, which killed four soldiers and caused some damage, "should neither be downplayed nor exaggerated", he said.

Iranian President Masoud Pezeshkian said Iran was not looking for war but would give an "appropriate response".

US President Joe Biden called for a halt to escalation, which has raised fears of a wider Middle East war arising from the year-old Israeli-Hamas conflict in Gaza and Israel's thrust into south Lebanon to stop Hezbollah rocketing northern Israel.

Separately, Israeli Defence Minister Yoav Gallant said Iran was no longer able to use its allies Hamas in Gaza and Hezbollah in Lebanon against Israel. The two groups "are no longer an effective tool" of Tehran, he said in a speech.

Gallant added that Hamas was no longer functioning as a military network in Gaza and that Hezbollah's senior command and most of its missile capabilities had been eliminated.

Hamas has repeatedly said it is still able to function militarily, and Israel has recently conducted major new operations in devastated north Gaza against what it calls regrouping Hamas militants.

Hezbollah has said its command structure remains intact and that it retains significant missile capabilities.

On Sunday, the Israeli military urged residents of 14 villages in southern Lebanon to evacuate immediately and move north of the Awali river.

An Israeli strike on Sidon, a city in coastal south Lebanon, killed at nine people and wounded 25 on Sunday, the country's health ministry said.

Elsewhere in the south, a strike on Zawtar al-Sharkiya killed three people and a Saturday bombing of Marjayoun killed five, it said.

In all, Israeli strikes killed 19 people in Lebanon on Saturday, the health ministry said. At least 2,672 people have been killed and 12,468 injured in the year since Israel and Hezbollah began exchanging rocket fire, it said late on Sunday.
