Israel launched a series of intense airstrikes in southern Lebanon early Sunday in what it said was a pre-emptive strike against Hezbollah.
The army said Hezbollah was planning to launch a heavy barrage of rockets and missiles toward Israel. The group had been promising to retaliate for Israel's assassination of Fouad Shukr, a top commander late last month.
Air raid sirens were reported throughout northern Israel, and Israel's Ben-Gurion international airport began diverting incoming flights and delaying takeoffs.
Soon afterwards, Hezbollah announced it had launched an attack on Israel with a “large number of drones” as an initial response to Shukr’s killing in a strike in Beirut’s southern suburbs last month.
Shukr's death in the airstrike was quickly followed by the assassination of Hamas leader Ismail Haniyeh in Tehran, which led to vows of reprisal against Israel by Iran.
Hezbollah said Sunday’s attack was targeting “a qualitative Israeli military target that will be announced later” as well as “targeting a number of enemy sites and barracks and Iron Dome platforms.”
Last week, Israel’s defense minister said he was moving more troops toward the Lebanese border in anticipation of possible fighting with the Iranian-backed group.
Israel’s military spokesman, Rear Adm. Daniel Hagari, said early Sunday: “In a self-defense act to remove these threats, the (Israeli military) is striking terror targets in Lebanon, from which Hezbollah was planning to launch their attacks on Israeli civilians.”
“We can see that Hezbollah is preparing to launch an extensive attack on Israel, while endangering the Lebanese civilians," he added, without providing details. ”We warn the civilians located in the areas where Hezbollah is operating to move out of harm’s way immediately for their own safety,” he added.
Israeli media cited the Israel Airports Authority for news of the flight cancellations. Flight-tracking data showed at least two El Al flights swinging far south and diverting after the announcement.
Israel's cabinet was to meet at 7 a.m. (0400 GMT), Prime Minister Benjamin Netanyahu's office announced.
Hezbollah began attacking Israel almost immediately after the war with Hamas erupted on Oct. 7 with a Hamas cross-border attack. Israel and Hezbollah have been exchanging fire nearly daily, displacing tens of thousands of people on both sides of the border and raising fears that the fighting could escalate into all-out war. But until Sunday, both sides have been careful to avoid a broader conflagration.
