The Israeli military announced that its air defense systems were intercepting a "threat" originating from Iran, calling on the public to adhere to home front instructions. Sirens sounded across wide areas of northern Israel following missile launches.
Israeli media reported explosions heard in central Israel, while Channel 12 said four missiles were launched and intercepted. The military noted the detection of an additional salvo of missiles heading toward Israel.
Israel's Home Front Command confirmed sirens were activated in the Golan Heights, Tiberias, Safed, Afula, Nazareth, Karmiel, and southern Haifa.
Later, the Israeli military spokesman stated: "We intercepted all the missiles launched by Iran at Israel tonight."
Threats and Closures
Separately, CNN quoted an Israeli source saying that Prime Minister Benjamin Netanyahu was holding security consultations in light of the developments.
Channel 12 reported that the Education Minister decided to close schools "throughout Israel" tomorrow due to the ongoing security escalation, while National Security Minister Itamar Ben-Gvir said: "Tehran must burn tonight."
The channel quoted an Israeli official saying Iran "sought to impose a new equation," adding that Israel "cannot allow that."
The Israeli Broadcasting Corporation cited sources stating that Tel Aviv was preparing to respond to the latest missile launches from Iran, signaling further escalation.
Axios also quoted an Israeli official confirming that Tel Aviv would respond to the Iranian attack, while a US official said President Donald Trump had been briefed on the developments and escalation between Iran and Israel.
On the Iranian side, the Iranian Civil Aviation Organization announced the closure of the western part of the country's airspace until further notice.
Meanwhile, a Baghdad airport source told Al Jazeera that Iraqi airspace was closed to air traffic, while Syrian civil aviation announced a temporary closure of southern air corridors and a 12-hour suspension of operations at Damascus International Airport.
Iranian Warning
In turn, the commander of Iran's "Khatam al-Anbiya" headquarters warned that Iran would launch "destructive attacks" on Israel and its supporters if operations expanded in Lebanon or if there was a response to Iran's recent actions.
The Iranian military official called on Israelis to halt attacks on southern Lebanon and Beirut's southern suburbs, asserting that Tehran had previously warned against striking occupied territories if the strikes continued or expanded.
The commander of the IRGC Aerospace Force said: "The promise has been fulfilled," while Iranian television reported a third wave of missiles launched toward occupied territories.
Fars News Agency quoted the IRGC as saying it had targeted the Ramat Air Base with ballistic missiles.
The IRGC added: "Our acceptance of a ceasefire was conditional on a ceasefire on all fronts. The current operation is a warning, and the responses will be broader and include all American and Israeli targets."
Meanwhile, the account of Iranian Supreme Leader Mojtaba Khamenei on X reposted a previous tweet affirming that "the policy of the Islamic Republic, following in the footsteps of its founder and previous leaders, is to continue supporting resistance" against Israel and the United States.
This escalation follows previous Iranian threats to respond to the raid that targeted Beirut's southern suburbs earlier, which preliminary data said resulted in casualties, amid ongoing tensions despite a fragile ceasefire in effect since last April.
Also on Sunday, Iranian parliament spokesman Ebrahim Rezaei, of the National Security and Foreign Policy Committee, threatened Israel with a response to the raid on Beirut's southern suburbs.
