Benjamin Netanyahu has summoned his war cabinet for the second time in less than 24 hours to weigh a response to Iran's weekend missile and drone attack.
Israelis are awaiting word on how Prime Minister Benjamin Netanyahu will respond to Iran's first-ever direct attack on their country as international pressure for restraint grew amid fears of an escalation of conflict in the Middle East.
Netanyahu on Monday summoned his war cabinet for the second time in less than 24 hours to weigh a response to Iran's weekend missile and drone attack, a government source said.
Israel's military Chief of Staff Herzi Halevi said the country would respond. He provided no details.
"This launch of so many missiles, cruise missiles, and drones into Israeli territory will be met with a response," he said at the Nevatim Airbase in southern Israel, which sustained some damage in Saturday night's attack.
Israeli Defence Minister Yoav Gallant has indicated retaliation against Iran is not imminent.
Israel remained on high alert, but authorities lifted some emergency measures that had included a ban on some school activities and limits on large gatherings.
The prospect of Israeli retaliation has alarmed many Iranians already enduring economic pain and tighter social and political controls since protests in 2022-23.
Iran launched the attack in retaliation for what it says was an April 1 Israeli airstrike on its embassy compound in Damascus, and signalled that it does not seek further escalation.
While the attack caused no deaths and limited damage, it has increased fears of open warfare between the long-time foes and fuelled concerns that violence rooted in the Gaza war is spreading.
US President Joe Biden told Netanyahu at the weekend that the United States, which helped Israel blunt the Iranian attack, will not participate in an Israeli counter-strike.
I condemn Iran's attacks in the strongest possible terms and reaffirm America's ironclad commitment to the security of Israel.
Since the war in Gaza began in October, clashes have erupted between Israel and Iran-aligned groups in Lebanon, Syria, Yemen and Iraq. Israel said four of its soldiers were wounded hundreds of metres inside Lebanese territory overnight.
It appeared to be the first such known incident since the Gaza war erupted, although there have been months of exchanges of fire between Israel and Lebanon's armed group Hezbollah.
"We're on the edge of the cliff and we have to move away from it," Josep Borrell, the European Union's foreign affairs chief, told Spanish radio station Onda Cero. "We have to step on the brakes and reverse gear."
French President Emmanuel Macron, German Chancellor Olaf Scholz and British Foreign Secretary David Cameron made similar appeals.
Washington and United Nations Secretary-General Antonio Guterres also have called for restraint.
White House national security spokesman John Kirby declined on Monday to say if Biden urged Netanyahu in talks on Saturday night to exercise restraint in responding to Iran.
"We don't want to see a war with Iran. We don't want to see a regional conflict," Kirby told a briefing, adding that it was for Israel to decide "whether and how they'll respond."
Russia has refrained from publicly criticising its ally Iran but has also urged restraint.
"Further escalation is in no one's interests," Kremlin spokesman Dmitry Peskov said.
Iran mounted its attack after the April 1 killing in Damascus of seven Iranian Revolutionary Guards officers, including two senior commanders. Israel neither confirmed nor denied carrying out the strike.
Iran's retaliatory attack, involving more than 300 missiles and drones, caused modest damage in Israel and wounded a 7-year-old girl. Most were shot down by Israel's Iron Dome defence system and with help from the US, Britain, France and Jordan.
In Gaza itself, where more than 33,000 Palestinians have been killed in the Israeli offensive according to Gaza health ministry figures, Iran's action drew applause.
Israel began its campaign against Hamas after the Palestinian militant group attacked Israel on October 7, killing 1,200 people and taking 253 hostages by Israeli tallies.
British Prime Minister Rishi Sunak said the Group of Seven major democracies were working on a package of coordinated measures against Iran.
"I spoke to my fellow G7 leaders, we are united in our condemnation of this attack," Sunak said in parliament.
Iranian Foreign Minister Hossein Amirabdollahian said Tehran had informed the US that the attack on Israel would be limited and for self-defence, and that regional neighbours were informed 72 hours in advance.
