IDF Expands Gaza Tunnel Strikes, Eyes Larger Lebanon Operation
Around 14:02 UTC on 11 May 2026, the Israel Defense Forces reported demolishing four Hamas tunnels in southern Gaza, including one linked to past hostage detentions. Israeli media the same day said the military is preparing to scale up operations in southern Lebanon amid ongoing Hezbollah ceasefire violations.
Key Takeaways
- On 11 May, the IDF said it had recently destroyed four Hamas tunnels in southern Gaza, one tied to previous hostage holding.
- Israeli military sources indicate preparations to expand operations in southern Lebanon due to continued Hezbollah ceasefire violations.
- Concurrently, the IDF struck multiple villages in southern Lebanon and Hezbollah claimed anti‑tank missile hits on IDF armor at Bayt al‑Sayyad.
- Lebanon’s Health Ministry reports 2,879 killed and 8,730 injured from Israeli attacks since 2 March.
- The combined Gaza and Lebanon developments point to a potential widening of Israel’s northern front.
At approximately 14:02 UTC on 11 May 2026, the Israel Defense Forces (IDF) announced that it had “recently” demolished four cross‑border tunnels used by Hamas in the southern Gaza Strip. One of the tunnels was specifically described as a facility previously used by Hamas to hold hostages, underscoring the continued focus of Israeli operations on subterranean infrastructure associated with the militant group’s warfighting and detention capabilities.
On the same day, Israeli Channel 12, citing senior military sources, reported that the IDF is preparing to expand its military activities in southern Lebanon. Separately, around 12:40–13:01 UTC, further reporting indicated that the army is intensifying strikes in Lebanese villages including Arnoun, Al‑Namireh, Zboudine, and Rihan, in what appears to be a step‑up in pressure on Hezbollah positions near the border.
The Lebanese side of the conflict is already exacting a heavy toll. The Lebanese Ministry of Health announced at around 13:41 UTC that the death count from Israeli attacks since 2 March has risen to 2,879, with 8,730 people wounded—an increase of over 30 fatalities in a single day. Around the same time, channels linked to Hezbollah reported the use of advanced anti‑tank guided missiles, likely 9M133‑1 Kornet‑E/Dehlavieh systems, to strike Israeli armored vehicles at Bayt al‑Sayyad. Other reports in the past 48 hours confirmed the killing of Ahmad Balout, the commander of Hezbollah’s elite Radwan Force, in an Israeli airstrike on Beirut’s Dahieh district.
In Gaza, the destruction of four tunnels signals that Israeli ground and engineering operations remain ongoing despite international calls to wind down large‑scale hostilities. Tunnels have long been central to Hamas’s military doctrine, used for smuggling, surprise attacks, and detaining hostages out of reach of aerial surveillance. Targeting a tunnel known to have held captives is likely to be highlighted by Israel as both a security measure and a justification for sustained deep operations in the Strip.
Key players include the IDF and the Israeli political leadership, Hamas operatives in southern Gaza, Hezbollah’s military wing in southern Lebanon, and civilian populations on both fronts. The IDF’s apparent readiness to enlarge the Lebanon operation reflects a judgement that low‑intensity cross‑border fire and sporadic strikes are no longer sufficient to deter or degrade Hezbollah’s capabilities.
The shifting operational balance matters because a broader campaign in southern Lebanon risks triggering a much wider conflict involving Iran and possibly drawing in Western actors. Hezbollah is Iran’s most capable regional proxy, and significant attrition to its leadership or strategic assets could provoke Tehran to use other tools—including support to allied militias elsewhere—to pressure Israel and its backers.
Regionally, escalating IDF strikes, Hezbollah’s anti‑armor activity, and the high civilian casualty figures in Lebanon are likely to generate renewed diplomatic pressure at the UN Security Council and from Arab states. The situation in the occupied West Bank remains volatile as well: on 11 May, Israeli forces conducted a raid at Qalandiya refugee camp in which a Palestinian fighter was killed and another man seriously wounded, demonstrating that the conflict still has multiple active theaters.
Outlook & Way Forward
Over the coming days, observers should expect further probing actions along the Israel‑Lebanon border as both sides test red lines. For Israel, “expansion” could mean deeper and more sustained air and artillery strikes, limited ground incursions to clear launch sites, or in a more escalatory scenario, a structured ground campaign to push Hezbollah units away from the frontier zones. Each of these options carries increased risk of casualties and international pushback.
On the northern front, key indicators will include the scale and depth of IDF strikes inside Lebanon, Hezbollah’s rate of cross‑border fire and anti‑armor engagements, and any signs of Iranian guidance or material support being stepped up. The death of the Radwan Force commander may incentivize Hezbollah to seek a high‑profile retaliatory action, raising the chance of attacks beyond the immediate border area.
In Gaza, continued tunnel demolitions suggest a long‑term Israeli intent to systematically degrade Hamas’s underground network, even if broader maneuver operations are eventually reduced. Intelligence collection should focus on whether tunnel destruction is accompanied by political moves—such as prisoner exchanges or ceasefire proposals—that could recalibrate the hostage issue.
Diplomatic avenues remain constrained but not closed. European actors, already moving naval assets to protect maritime routes, may intensify diplomatic efforts to prevent a full‑scale northern front. The risk is that cumulative incidents—such as a mass‑casualty strike, successful deep Hezbollah attack, or mis‑hit on international peacekeepers—could trigger rapid escalation before diplomacy catches up.
