Military chief of staff Herzi Halevi had promised that Saturday night's launch of more than 300 missiles, cruise missiles and drones from Iran at Israeli territory "will be met with a response" but gave no details.
While the attack caused no deaths and little damage, thanks to the air defences and countermeasures of Israel and its allies, it has increased fears that violence rooted in the Gaza war is spreading with the risk of open war between long-time foes Iran and Israel.

Iran launched the attack in retaliation for an air strike on its embassy compound in Damascus on April 1 attributed to Israel but has signalled that it now deems the matter closed.
An Israeli government source said the war cabinet session scheduled for Tuesday had been put off until Wednesday, without elaborating.
US President Joe Biden told Israeli Prime Minister Benjamin Netanyahu at the weekend that the United States, Israel's main protector, would not participate in an Israeli counter-strike.
Together with European allies, the US instead strove on Tuesday to toughen economic and political sanctions against Iran in an attempt to dissuade Israel from violent retaliation.
Israeli Foreign Minister Israel Katz said he was "leading a diplomatic attack," writing to 32 countries to ask them to place sanctions on Iran's missile programme and follow the US in proscribing its dominant military force, the Revolutionary Guard Corps, as a terrorist group.
Treasury Secretary Janet Yellen said the US would use sanctions and work with allies to keep disrupting Iran's "malign and destabilising activity".

She told a news conference in Washington DC that all options to disrupt Iran's "terrorist financing" were on the table, and that she expected further sanctions against Iran to be announced in coming days.
European Union foreign ministers scheduled a video meeting on the Middle East for Tuesday.
Last autumn, Germany campaigned with France and other EU partners to extend the bloc's existing sanctions regime against Iran that targets drone production.
German Foreign Minister Annalena Baerbock said on Tuesday that several EU members had now promised to look again at extending those sanctions, announcing that she would head to Israel within hours to discuss how to prevent an escalation.
UK Prime Minister Rishi Sunak said on Monday the Group of Seven countries was working on a package of measures against Iran; Italy, which has the G7 presidency, suggested any new sanctions would target individuals.
Iranian Deputy Foreign Minister Ali Bagheri Kani had told state TV on Monday night that Iran's response to any Israeli counterattack would come in "a matter of seconds, as Iran will not wait for another 12 days to respond".
The prospect of Israeli retaliation has alarmed many Iranians already enduring economic pain and tighter social and political controls since major protests in 2022-23.
