Israeli forces launched a ground incursion into southern Lebanon early Tuesday, deploying additional troops to seize strategic positions along the border. The operation, described by the Israeli military as a forward defense measure under Operation Roaring Lion, aims to protect border communities from Hezbollah attacks following the group's rocket and drone barrages that began late Sunday.

Defense Minister Israel Katz authorized the military to advance and take control of additional areas, stating the moves would prevent Hezbollah fire on Israeli settlements. IDF spokesman Lt. Col. Nadav Shoshani said troops were positioned at the borderline in a defensive manner to safeguard civilians and key sites. A small force, including a tank and three bulldozers, crossed from Metula toward the Tal al-Nahas area between Kfarkela and Burj al-Muluk, marking a visible advancement in the eastern sector.

The incursion builds on five positions Israel has held in southern Lebanon since a November 2024 ceasefire following a yearlong war with Hezbollah. Overnight, the IDF conducted airstrikes on Hezbollah targets in Beirut's southern suburbs, including Haret Hreik in Dahiyeh, and southern Lebanon, hitting command centers, weapons storage, and intelligence facilities. Lebanon's state media reported at least 52 people killed and 154 injured in strikes on Beirut and the south since Monday.

Hezbollah responded with a drone swarm targeting Ramat David airbase and missiles at a Haifa military site on Tuesday morning, declaring an end to restraint. A senior official stated Israel sought open war, so "let it be an open war." Most projectiles landed in open areas or were intercepted, with no Israeli casualties reported.

The Lebanese army withdrew from seven forward border positions to avoid clashes, relocating farther back after U.S. notification of the incursion. President Joseph Aoun urged international pressure on Israel to halt attacks and return to ceasefire talks, while reiterating a ban on Hezbollah military activity.

The escalation coincides with intensified U.S.-Israeli strikes on Iran, prompting Hezbollah's involvement. IDF Chief Lt.-Gen. Eyal Zamir vowed the operation would deliver a devastating blow to Hezbollah, enforcing its disarmament. Israel issued evacuation orders for 59 Lebanese areas, displacing thousands who fled to Beirut schools and roads.

Northern Command indicated no immediate plans for a broader invasion, pending developments with Iran. Hezbollah, weakened by prior losses and reduced Iranian support, has refrained from full arsenal use.
