Air raid sirens sounded across central Israel, including at the Tel Aviv international airport, shortly after Prime Minister Benjamin Netanyahu landed after a trip to the U.S.

The Israeli military said a missile launched from Yemen was intercepted shortly after the sirens were heard. There were no reports of injuries.

A prominent general in Iran's paramilitary Revolutionary Guard died in an Israeli airstrike that killed Hezbollah leader Sayyed Hassan Nasrallah in Beirut's southern suburbs, Iranian media reported Saturday.

The killing of Gen. Abbas Nilforushan marks the latest casualty suffered by Iran as the nearly yearlong Israel-Hamas war in the Gaza Strip teeters on the edge of becoming a regional conflict. His death further ratchets up pressure on Iran to respond, even as Tehran has signaled in recent months that it wants to negotiate with the West over sanctions crushing its economy.

Hezbollah launched more than two dozen projectiles toward Israel Saturday morning, triggering sirens in more than 100 cities and towns across Israel and the Israeli-occupied West Bank.

The Israeli military said a surface-to-surface missile was fired from Lebanese territory and fell in an open area in central Israel. Israeli media said the missile fell in the sea.

Israel’s military said it carried out a “precise strike” on Hezbollah’s central headquarters in south Beirut on Friday.

Israeli military spokesperson Daniel Hagari announced the strike in a televised address.

The Israeli military said it struck the headquarters of Hezbollah in the southern suburbs of Beirut on Friday, after violent explosions rocked Dahieh and were heard across Beirut.

"The IDF (Israeli army) carried out a precise strike on the central headquarters of the terrorist organization Hezbollah in Dahieh," military spokesman Rear Admiral Daniel Hagari said in a televised statement.

An Israeli security official said he expects a possible war against Hezbollah would not last for as long as the current war in Gaza because the Israeli military’s goals are much narrower.

The official said Israel has vowed to dismantle Hamas' military and political regime in Gaza, but the goal in Lebanon is just to push Hezbollah away from the border with Israel. That is “not a high bar like Gaza” in terms of operational objectives, said the official, who spoke on condition of anonymity in line with military briefing guidelines.

In 2006, after a bruising monthlong war between Israel and Lebanon's powerful Hezbollah, the United Nations Security Council unanimously voted for a resolution to end the conflict and pave the way for lasting security along the border.

But while there was relative calm for nearly two decades, Resolution 1701's terms were never fully enforced.

Israel and Hezbollah each have strong incentives to heed international calls for a cease-fire that could avert all-out war — but that doesn't mean they will.

Hezbollah is reeling after a sophisticated attack on personal devices killed and wounded hundreds of its members. Israeli airstrikes have killed two top commanders in Beirut in less than a week, and warplanes have pounded large parts of Lebanon, killing over 600 people.

When she first heard about the evacuation warnings Israel was sending to residents of Lebanon, Aline Naser's thoughts immediately turned to Gaza.

For the past year, the 26-year-old Beirut resident has been following with horror the reports about besieged Palestinians in the Gaza Strip ordered to move from one place to the other, fleeing to "humanitarian zones" only to be bombed and ordered to leave again.

Norway has issued an international wanted notice for a man linked to a Bulgaria-based company that may have been involved in the dissemination of exploding electronic devices to the militant Hezbollah group that killed dozens and wounded thousands in Lebanon last week.

The notice is part of a multi-country investigation trying to piece together how thousands of pagers and walkie-talkies were rigged to explode and their trail to Lebanon.
