VIDEO: Iran fires missiles at Israel after Beirut strike, raising fears of wider regional conflict

The Israeli military said it had so far intercepted all missiles fired by Iran on Sunday, while warning that the Islamic republic had launched a new salvo.

"The IDF intercepted all missiles from Iran thus far. The IDF has currently identified additional launches fired toward the State of Israel," the military said. "The Aerial Defense Array is currently identifying and intercepting threats."

Iran's Revolutionary ​Guards ⁠said their attacks ‌on ‌Israel on ‌Sunday evening ⁠were a "warning" of a broader response that ​would encompass ‌all US and ⁠Israeli targets in the region ​if "aggressions" ‌are ‌repeated.

Iran's military central command said that Israel's latest strike on the southern Beirut suburbs had "crossed all red lines", demanding a halt to its campaign in Lebanon.

"The Israeli army must stop its attacks on southern Lebanon and the suburbs, and if it expands its attacks to that region or responds to Iran's action, it will face more devastating and regrettable blows," said General Ali Abdollahi, the head of the Khatam Al-Anbiya command, without directly mentioning missile salvos that Israel said it was intercepting.

Air raid sirens sounded in Israel on Sunday as its military worked to intercept barrages of incoming Iranian missiles for the first time since an April ceasefire took hold in the Middle East war.

The Israeli army reported the attack just hours after Tehran had threatened to retaliate for a new Israeli strike on Beirut.

An April 8 ceasefire had halted major hostilities between Iran, Israel and the US, but efforts to turn the truce into a settlement have repeatedly stalled, and Sunday's launches were sure to further dampen hopes for a lasting peace, as the Middle East war reached its 100th day.

Tehran has insisted any deal to permanently end the war must also halt the parallel conflict in Lebanon, where Israel is pursuing a campaign against the Iran-backed movement Hizbollah, and had warned that any new attacks on Beirut would trigger a "full-scale resumption" of hostilities.

On Sunday, Israeli Prime Minister Benjamin Netanyahu's office announced that the army had "struck a militant command centre in Beirut's Dahiyeh district, in response to Hezbollah's fire towards Israeli territory".

The raid killed two people and wounded 20 more, Lebanon's health ministry said.
