IDF Expands Lebanon Buffer Zone Amid Hezbollah Attacks

The Israel Defense Forces (IDF) is deepening its presence in southern Lebanon, enacting what officials describe as an expanded buffer zone, although facing continued rocket and drone attacks from Hezbollah targeting northern Israel. The escalation comes after a period of heightened tensions following strikes by Israel and the United States against Iranian targets earlier this month.

The IDF stated Tuesday that troops are undertaking a “targeted ground operation” to broaden the “forward defense area,” aiming to mitigate the threat of rocket fire on Israeli communities. This move follows a warning issued to Lebanese civilians to evacuate areas south of the Zahrani River, a directive repeated Tuesday morning. Lebanese authorities report that over one million people have registered as displaced due to the ongoing conflict.

The current fighting represents a significant escalation in a conflict that has simmered since October 2023, when Hezbollah initiated attacks on Israel following the Hamas-led invasion of southern Israel. While a November 2024 ceasefire brought a period of relative calm, hostilities resumed on March 2, with Hezbollah launching attacks in response to the killing of Iran’s Supreme Leader Ali Khamenei. The IDF estimates Hezbollah has been launching approximately 100 rockets daily, alongside over 100 drones throughout the period.

Expanding Operations and Hezbollah’s Response

Israeli military sources indicate that Hezbollah is launching attacks from positions deeper within southern Lebanon, rather than from areas immediately adjacent to the border. In response, the IDF has carried out extensive airstrikes and artillery shelling before advancing troops into the region. On Tuesday, dawn airstrikes targeted locations in the Dahiyeh, a Hezbollah stronghold in southern Beirut, with prior evacuation warnings issued to residents. Lebanese state media reported strikes on the Kafaat and Haret Hreik areas, as well as a residential building in Doha Aramoun.

Overnight and into Tuesday morning, sirens sounded in multiple northern Israeli towns, signaling incoming rocket and drone attacks. While no injuries were reported Tuesday, six people were wounded Monday evening when a rocket struck Nahariya. The IDF has conducted numerous airstrikes against Hezbollah targets in the Dahiyeh over the past week, repeatedly urging civilians to evacuate the area.

The Broader Context: Iran and Regional Implications

The renewed conflict with Hezbollah is occurring against the backdrop of a wider, evolving confrontation with Iran. Israeli officials have emphasized the interconnectedness of these conflicts, with IDF Chief of Staff Lt. Gen. Eyal Zamir stating that the “shockwaves” of Israel’s strikes in Iran are being felt by Hezbollah. Zamir asserted that weakening Iran’s capabilities will also diminish Hezbollah’s arming and financing. He also claimed that over 400 Hezbollah members, including senior officers, have been killed since the recent escalation.

This perspective aligns with analysis from Sarit Zehavi, head of Alma, a think tank based in northern Israel, who told RFE/RL that “The campaign against Iran was meant to deal with our very existence in the region, and Hezbollah is part of that.” As RFE/RL reported, the conflict with Hezbollah is considered an integral part of Israel’s broader strategy against Iran.

Humanitarian Impact and Displacement

The fighting is having a devastating impact on civilian populations. At least 886 people have been killed in Israeli strikes in Lebanon, according to Lebanese authorities, with the World Health Organization reporting that at least 98 of those killed were children. The displacement of over a million people in Lebanon is creating a significant humanitarian crisis. The IDF has issued wide-scale evacuation warnings, urging civilians to move north of the Zahrani River.

Potential for Further Escalation and Diplomatic Efforts

Despite the ongoing military operations, there have been reports of potential diplomatic efforts to de-escalate the situation. Reports have surfaced regarding possible talks between Israel and the Lebanese government, which has pledged to disarm Hezbollah under the terms of a November 2024 agreement. However, Israeli Foreign Minister Gideon Sa’ar has denied these reports.

Defense Minister Israel Katz has even threatened to seize territory in Lebanon if attacks persist. The IDF continues to prepare for a potential large-scale ground operation in southern Lebanon, aimed at uprooting Hezbollah, though the timing and scope of such an operation remain unclear.

Hezbollah’s Arsenal and Past Conflicts

Prior to the 2024 ceasefire, the IDF estimated that Hezbollah retained as much as a third of its pre-war missile stockpile. CNN reported that before the 2024 conflict, Israel believed Hezbollah possessed an arsenal of some 125,000-150,000 rockets, though estimates varied. The IDF claimed to have degraded this arsenal by 80 percent during the previous conflict.

Israel and Hezbollah have a long history of conflict, dating back to the 1980s. The current fighting represents the latest chapter in a decades-long struggle between the two sides. The IDF is now focused on severing the operational linkage between Iran and Hezbollah, according to military sources. JNS.org reported on this effort Thursday.
