Twenty days after Hezbollah drew Lebanon into an open conflict with Israel, concerns are mounting over the group’s potential shift inward as military pressure intensifies along the southern front and Israeli operations expand.

With Israeli forces advancing over more than 120 square kilometers, destroying bridges along the Litani River and announcing plans to accelerate the demolition of homes in frontline villages, analysts say two closely linked questions are emerging: whether Hezbollah will seek to tighten its domestic grip to offset battlefield losses, and whether the planned establishment of a large camp for displaced people in Karantina could carry broader security risks.

The connection between the two developments, observers argue, is not speculative but reflects a pattern seen in previous crises. When faced with external pressure, Hezbollah has historically moved to consolidate control internally; not necessarily through large-scale violence, but by strengthening its security presence, expanding its areas of influence, and reorganizing its support base.

That concern has brought particular attention to Karantina, a sensitive area near the Beirut port. Work is already underway to convert a warehouse in a commercial zone near the fish market into a shelter, with plastic partitions being installed to create makeshift rooms. The site is expected to initially accommodate more than 1,000 displaced people.

While the project has been framed as a humanitarian response, critics warn it carries significant strategic and security implications. Karantina lies adjacent to the Beirut port, one of the country’s most critical economic and sovereign assets, and any instability in the area could have immediate repercussions for both the economy and security in the capital.

Some fear the move could effectively place pressure on Beirut from its coastal flank, potentially complicating access to key regions such as Metn and Keserwan if internal tensions escalate.

These concerns are compounded by the likelihood that many displaced people may have no homes to return to, as destruction continues in southern Lebanon. Reconstruction efforts remain uncertain, with limited funding available domestically or from Gulf countries, raising the prospect that what is intended as a temporary solution could become permanent, echoing past cases where informal settlements evolved into entrenched enclaves, such as in Ouzai and parts of Nabaa.

The situation is further complicated by Hezbollah’s public acknowledgment of direct coordination with Iran’s Islamic Revolutionary Guard Corps, fueling fears that large concentrations of displaced people could become a factor in any future internal instability.

Opposition to the Karantina plan has begun to surface. The Beirut port truck owners’ union issued a statement rejecting any use of land adjacent to the port to house displaced people, warning of “serious risks” to both the residents and the functioning of the port.

The union said that “any gathering of this scale near a vital and sensitive facility like the Beirut port could expose it to major security threats, particularly under the current exceptional circumstances,” adding that such a move could endanger displaced people, port workers, and others in the area.

Beyond location, concerns also stem from the nature of camps in Lebanon, which have historically proven difficult to manage from a security standpoint, especially in the absence of clear governance. The concentration of thousands of displaced people in a confined area, amid political divisions, could create a volatile environment.

Past incidents — including the May 7 clashes, the so-called “black shirts” episodes, and violence in Ain al-Remmaneh — are frequently cited as examples of how quickly tensions can escalate when armed actors are involved.

There are also fears of a potential military dimension. In the context of ongoing hostilities with Israel, any area suspected of hosting Hezbollah-linked infrastructure or personnel could become a target. A camp located near the port, in a densely populated area, could place civilians at heightened risk.

Karantina itself carries historical weight. The neighborhood is closely associated with episodes of violence during Lebanon’s civil war, and the reintroduction of a large camp in the area risks reviving old fears and fueling social tensions. Early signs of public opposition suggest growing unease among residents, particularly in nearby Ashrafieh.

Taken together, analysts say the developments point to a potentially dangerous overlap between humanitarian needs and security realities. If Hezbollah moves to tighten its internal control while a large camp is established in a sensitive location, the site could evolve — intentionally or not — into a zone of influence, a flashpoint, or a bargaining chip in Lebanon’s internal balance of power.

Rather than resolving the displacement crisis, critics warn, the plan could deepen broader concerns about the stability of the capital and exacerbate tensions between Hezbollah and other Lebanese factions.

As the situation unfolds, Beirut faces a critical test: whether it can prevent a scenario in which the capital is drawn into a wider confrontation, transforming it into an open arena for competing forces.
