Booms and air raid sirens sounded in Jerusalem early Sunday after Iran launched dozens of drones and ballistic missiles toward Israel in an unprecedented revenge mission that pushed the Middle East ever closer to a regionwide war.

The attack marked the first time Iran has launched a direct military assault on Israel, despite decades of enmity dating back to the country's 1979 Islamic Revolution. Condemnation was swift, with France saying that "Iran has crossed a new threshold with regard to its destabilizing activities and is risking a potential military escalation." Britain called the attacks "reckless."

There was no immediate word from authorities on whether any explosions were an incoming attack. Air raid sirens were reported in numerous places, including northern Israel, southern Israel, the northern West Bank and the Dead Sea near the Jordanian border. Israel's Magen David Adom rescue service said it was treating a 10-year-old boy in critical condition in the Bedouin area in the Arad region but provided no details.

U.S. forces downed some of the Iran-launched drones flying toward Israel, according to a U.S. defense official and two U.S. officials who spoke on condition of anonymity to discuss the matter. The defense official said the effort to intercept the attack was ongoing.


What You Need To Know

  • Iran has launched an attack on Israel — reportedly consisting of both ballistic missiles and military drones — in retaliation for an alleged Israeli attack on an iranian embassy in Syria last week

  • Explosions have been heard in the skies over Jerusalem — an Israeli military spokesperson earlier said that the military is monitoring the threat, noting that its air defenses were prepared and ready to respond

  • Two Iranian generals were killed in an April 1 strike on an Iranian consular building; Saturday's attack, an official Iran-run social media account said, was in response to that strike, for which it held Israel responsible. "The matter can be deemed concluded," the post said, warning that further military response "will be considerably more severe"

  • President Joe Biden cut short a trip to Delaware to meet with his national security team to discuss issues in the Middle East; after, he affirmed that American support for Israel's defense is "ironclad"
  • U.S. officials confirmed that American forces have intervened to down Iranian drones attacking Israel, saying that the effort to intercept the attack is ongoing

Israel's military said over 100 drones had been fired. It didn't mention ballistic missiles, which are less easily shot down, but Iran said they were part of the attack.

"We are monitoring the threat," the Israeli military's spokesman, Rear Adm. Daniel Hagari, announced in a nationwide television address.

Iran had vowed revenge since an April 1 airstrike in Syria killed two Iranian generals inside an Iranian consular building. Iran accused Israel of being behind the attack. Israel hasn't commented on it.

Israel and Iran have been on a collision course throughout Israel's six-month war against Hamas militants in the Gaza Strip. The war erupted after Hamas and Islamic Jihad, two militant groups backed by Iran, carried out a devastating cross-border attack on Oct. 7 that killed 1,200 people in Israel and kidnapped 250 others. An Israeli offensive in Gaza has caused widespread devastation and killed over 33,000 people, according to local health officials.

Almost immediately after the war erupted, Hezbollah, an Iranian-backed militant group in Lebanon, began attacking Israel's northern border. The two sides have been involved in daily exchanges of fire, while Iranian-backed groups in Iraq, Syria and Yemen have launched rockets and missiles toward Israel.

In a statement carried late Saturday by Iran's state-run IRNA news agency, the country's paramilitary Revolutionary Guard acknowledged launching "dozens of drones and missiles towards the occupied territories and positions of the Zionist regime."

In a later statement, the Revolutionary Guard issued a direct warning to the U.S.: "The terrorist U.S. government is warned any support or participation in harming Iran's interests will be followed by decisive and regretting response by Iran's armed forces."

IRNA also quoted an anonymous official saying ballistic missiles were part of the attack. A ballistic missile moves on an arch trajectory, heading up into space before gravity brings the weapon down at a speed several times faster than the speed of sound.

Israel has missile defense systems capable of targeting ballistic missiles. However, in a massive attack involving multiple drones and missiles, the likelihood of a strike making it through is higher.

Iran has a vast arsenal of drones and missiles. Online videos shared by Iranian state television purported to show delta-wing-style drones resembling the Iranian Shahed-136s long used by Russia in its war on Ukraine. The slow-flying drones carry bombs. Ukraine has successfully used both surface-to-air missiles and ground fire to target them.

Israel has a multilayered air-defense network that includes systems capable of intercepting a variety of threats including long-range missiles, cruise missiles, drones and short-range rockets.

Hagari, the army spokesman, said Israel was "prepared and ready." But he cautioned that the air defenses are not 100% effective and urged the public to heed safety instructions.

The army ordered residents in the Golan Heights — near the Syrian and Lebanese borders — as well as the southern towns of Nevatim and Dimona and the Red Sea resort of Eilat "to stay near protective spaces until further notice." Dimona is home to Israel's main nuclear facility, and Nevatim has a major air base.

The army's Home Front Command canceled school on Sunday and limited public gatherings to no more than 1,000 people. Israel closed its airspace and canceled all flights.

Earlier Prime Minister Benjamin Netanyahu warned: "Whoever harms us, we will harm them."

In Washington, President Joe Biden cut short a weekend trip to his beach house in Delaware to return to the White House. He convened a meeting of the National Security Council on Saturday to discuss the unfolding attack, the White House said. In a social media post, Biden said that the U.S.'s commitment to Israel "is ironclad."

Earlier Saturday, U.S. Secretary of Defense Lloyd Austin spoke with Israeli Defense Minister Yoav Gallant to discuss regional threats, a DOD spokesperson announced.

According to a readout of the call, Austin reiterated "unwavering U.S. support for Israel's defense," and said that Israel could "count on full U.S. support to defend Israel" from any attacks by Iran or its regional proxies.

"The United States will stand with the people of Israel and support their defense against these threats from Iran," National Security Council spokesperson Adrienne Watson said in a statement.

Gen. Erik Kurilla, the head of the U.S. military's Central Command, was in Israel over the weekend consulting with Israeli defense officials about the Iranian threat. The Central Command oversees U.S. forces in the Middle East.

Iran's mission to the United Nations issued a warning to both Israel and the U.S. "Should the Israeli regime make another mistake, Iran's response will be considerably more severe," it wrote online. "It is a conflict between Iran and the rogue Israeli regime, from which the U.S. MUST STAY AWAY!"

For days, Iranian officials, including Supreme Leader Ayatollah Ali Khamenei, had threatened to “slap” Israel for its Syria strike.

In Iran's capital, Tehran, witnesses saw long lines at gas stations early Sunday as people appeared worried about what may come next. Dozens of hard-liners demonstrated in support of the attack at Palestine Square.

Lebanon's state-run National News Agency reported heavy Israeli airstrikes and shelling on multiple locations in south Lebanon following Iran's launch of drones. The Lebanese militant group Hezbollah said it launched "dozens" of Katyusha rockets at an Israeli military site in the Golan Heights early Sunday. It was not immediately clear if there was any damage.

Countries in the region began to close their airspace.
