Israel says attacks on Iran are 'nothing' compared with what is coming

Iran and Israel traded missiles and airstrikes on Saturday, the day after Israel launched a sweeping air offensive against its old enemy, killing commanders and scientists and bombing nuclear sites in a stated bid to stop it from building an atomic weapon.

Israeli Prime Minister Benjamin Netanyahu said Israel's strikes had set back Iran's nuclear programme possibly by years but rejected international calls for restraint, saying the attack would be intensified.

"We will hit every site and every target of the Ayatollahs' regime, and what they have felt so far is nothing compared with what they will be handed in the coming days," he said in a video message.

In Tehran, Iranian state TV reported that around 60 people, including 20 children, had been killed in an attack on a housing complex, with more strikes reported across the country. Israel said it had attacked more than 150 targets.

In Israel, air raid sirens sent residents into shelters as waves of missiles streaked across the sky and interceptors rose to meet them. At least three people were killed overnight. An Israeli official said Iran had fired around 200 ballistic missiles in four waves.

U.S. President Donald Trump has lauded Israel's strikes and warned of much worse to come unless Iran quickly accepts the sharp downgrading of its nuclear programme that the U.S. has demanded in talks that had been due to resume on Sunday.

But with Israel saying its operation could last weeks, and urging Iran's people to rise up against their Islamic clerical rulers, fears have grown of a regional conflagration dragging in outside powers.

The United States, Israel's main ally, helped shoot down Iranian missiles, two U.S. officials said.

"If (Supreme Leader Ayatollah Ali) Khamenei continues to fire missiles at the Israeli home front, Tehran will burn," Israeli Defence Minister Israel Katz said.

Iran had vowed to avenge Friday's Israeli onslaught, which gutted Iran's nuclear and military leadership and damaged atomic plants and military bases.

Tehran warned Israel's allies that their military bases in the region would come under fire too if they helped shoot down Iranian missiles, state television reported.

However, 20 months of war in Gaza and a conflict in Lebanon last year have decimated Tehran's strongest regional proxies, Hamas in Gaza and Hezbollah in Lebanon, reducing its options for retaliation.

Gulf Arab states that have long mistrusted Iran but fear coming under attack in any wider conflict have urged calm as worries about disruption to the region's crucial oil exports boosted the price of crude by about 7% on Friday.

Lawmaker and military general Esmail Kosari said Iran was reviewing whether to close the Strait of Hormuz, the exit point for oil shipped from the Gulf.

Iran's overnight fusillade included hundreds of ballistic missiles and drones, an Israeli official said. Three people, including a man and a woman, were killed and dozens wounded, the ambulance service said.

In Rishon LeZion, south of Tel Aviv, emergency services rescued a baby girl trapped in a house hit by a missile, police said, but later on Saturday Tel Aviv beaches were busy with people enjoying the weekend.

In the western suburb of Ramat Gan, near Ben Gurion airport, Linda Grinfeld described her apartment being damaged: "We were sitting in the shelter, and then we heard such a boom. It was awful."

The Israeli military said it had intercepted surface-to-surface Iranian missiles as well as drones, and that two rockets had been fired from Gaza.

In Iran, Israel's two days of strikes destroyed residential apartment buildings, killing families and neighbours as apparent collateral damage in strikes targeting scientists and senior officials in their beds.

Iran said 78 people had been killed on the first day and scores more on the second day, many of them when a missile brought down a 14-storey apartment block in Tehran.

State TV said 60 people were believed to have been killed there, though the figure was not officially confirmed.

It broadcast pictures of a building flattened into debris and the facade of several upper storeys lying sideways in the street, while slabs of concrete dangled from a neighbouring building.

"Smoke and dust were filling all the house and we couldn't breathe," 45-year-old Tehran resident Mohsen Salehi told Iranian news agency WANA after an overnight air strike woke his family.

Fars News agency said two projectiles had hit Mehrabad airport, located inside the capital, which is both civilian and military.

With Iran's air defences heavily damaged, Israeli Air Force chief Tomer Bar said "the road to Iran has been paved".

In preparation for possible further escalation, reservists were being deployed across Israel. Army Radio reported units had been positioned along the Lebanese and Jordanian borders.

Israel sees Iran's nuclear programme as a threat to its existence, and said the bombardment was designed to avert the last steps to production of a nuclear weapon.

A military official on Saturday said Israel had caused significant damage to Iran's nuclear facilities at Natanz and Isfahan, but had not so far taken on another uranium enrichment site, Fordow, dug into a mountain.

The official said Israel had "eliminated the highest commanders of their military leadership" and had killed nine nuclear scientists who were "main sources of knowledge, main forces driving forward the (nuclear) programme".

Tehran insists the programme is entirely civilian in line with its obligations under the nuclear Non-Proliferation Treaty (NPT) and that it does not seek an atomic bomb.

However, it has repeatedly hidden some part from international inspectors, and the International Atomic Energy Agency on Thursday reported it in violation of the NPT.

Iranian talks with the United States to resolve the nuclear dispute have stuttered this year.

The next meeting was set for Sunday but Iranian Foreign Minister Abbas Araqchi said on Saturday that continuing the talks while Israel's "barbarous" attacks lasted was unjustifiable.
