Israel's top military commander has vowed to respond to Iran's recent attack, despite appeals for restraint from world leaders concerned about escalating regional tensions.
During the six months of conflict between Israel and Gazans, Iranian proxies around the region have increased their assaults on Israel and its allies, claiming to act in solidarity with Palestinians.
Tensions were already high before Iran launched its first-ever assault on Israeli territory, firing hundreds of missiles and drones in retaliation for a deadly April 1 airstrike on the Iranian Consulate in Damascus.
"This launch of so many (Iranian) missiles, cruise missiles and UAVs into the territory of the State of Israel will be met with a response," Israeli armed forces chief Lieutenant General Herzi Halevi said Monday, addressing troops at the Nevatim airbase, which was hit in Iran's Saturday night barrage.
The Israeli army has said the majority of the weapons were shot down, with assistance from the U.S. and other allies, and the attack caused only minimal damage.
Western governments, including those that supported Israel in its defense, have warned against escalation.
Prime Minister Benjamin Netanyahu met with his War Cabinet late Monday to discuss the next steps, Israeli media reported.
Iran has previously said it would consider the matter "concluded" unless Israel retaliated.
Foreign Minister Hossein Amirabdollahian told his Chinese counterpart in a call on Tuesday that Iran was "willing to exercise restraint" and had no intention of further escalating tensions.
China's top diplomat, Wang Yi, said it was "believed that Iran can handle the situation well and spare the region further turmoil."
The United States has repeatedly appealed to China, a close partner of Iran and a top buyer of its U.S.-sanctioned oil, to use its influence over Tehran to manage tensions in the Middle East.
Israel on Monday issued its first official comment on the strike on the Iranian Consulate in Syria that prompted Tehran's weekend attack.
"These were people who engaged in terrorism against the State of Israel," Israeli military spokesperson Daniel Hagari said. "There was not a single diplomat there as far as I know."
The strike killed seven Iranian Revolutionary Guards, two of them generals.
Iran has portrayed its retaliatory missile and drone barrage as the first act in a tough new strategy.
The Iranian president's deputy chief of staff for political affairs, Mohammad Jamshidi, wrote that the "era of strategic patience is over," and further targeting Iranian personnel and assets "will be met with a direct and punishing response."
The head of the U.N.'s atomic watchdog revealed that Iran had temporarily closed its nuclear facilities over "security considerations" after launching its retaliatory attack.
International Atomic Energy Agency chief Rafael Grossi said the facilities were expected to reopen on Monday, but his inspectors would not return until Tuesday or when "we see that the situation is completely calm."
U.S. President Joe Biden has told Netanyahu that Washington would not offer military support for any retaliation against Iran, according to a senior U.S. official.
British Foreign Secretary David Cameron and French President Emmanuel Macron were among those urging restraint.
Secretary of State Antony Blinken said Washington did not "seek escalation, but we'll continue to support the defense of Israel."
U.S. House Speaker Mike Johnson announced that a vote on a fresh package of military aid for Israel could come as early as Friday.
The package has been stalled in the House by right-wing members of Johnson's Republican Party who oppose new military funding for Ukraine, which is also included in the bill.
Following the weekend's attacks, Israel's military said it would not be distracted from the ongoing war against Hamas in Gaza.
Fighter jets destroyed tunnels and military compounds where armed Hamas were located, the army said.
The Hamas' Oct. 7 incursion that triggered the latest conflict in Gaza resulted in the deaths of 1,200 people.
Israel's attacks have killed at least 33,797 people in Gaza, mostly women and children, according to the Health Ministry in the Hamas-run territory.
Israel estimates that 129 hostages were seized on Oct. 7.
At a White House meeting with Iraqi Prime Minister Mohamed Shia al-Sudani, Biden said: "We're committed to a cease-fire that will bring the hostages home and prevent the conflict spreading beyond what it already has."
Reflecting both the domestic pressure Biden is under and global calls for a cease-fire in Gaza, pro-Palestinian demonstrators blocked San Francisco's Golden Gate Bridge on Monday.
Israel's offensive against Hamas has triggered a humanitarian crisis in Gaza, with desperate shortages of food, medicines and drinking water.
The United Nations said it delivered a four-day supply of fuel to a bakery in northern Gaza on Sunday to enable it to resume operations in an area that "has recorded the highest levels of catastrophic hunger in the world."
