Israeli Strikes Kill Multiple Civilians in Gaza City as Hamas Warns of Ceasefire Collapse Risk

Civilian Deaths in Al-Zaytoun Strike

At approximately 16:17 UTC on 28 May 2026, Palestinian sources reported an explosion south of the Al-Zaytoun neighbourhood in Gaza City, with smoke rising from the site. According to reporting by Al-Alam News Network, occupation aircraft carried out the strike in a densely populated residential area south of the city. A subsequent report from The Cradle Media confirmed that one person was killed and several others were wounded when Israeli drones targeted a group of civilians in the Al-Zaytoun neighbourhood. The identity of the deceased and the full casualty count from that specific strike remained unconfirmed as of publication.

That strike occurred against the backdrop of a broader and deadlier incident hours earlier. According to Middle East Eye, an Israeli air strike hit a residential building in Gaza City, killing at least 10 people, including two children and two women. The timing and precise location of that strike were not specified in the source material, though it occurred in the same 24-hour window and was reported by the wire service as part of the same escalation pattern.

Hamas Warns of Ceasefire Breakdown

The strikes drew an immediate response from Hamas. According to Middle East Eye, the movement warned of the risk of the Gaza ceasefire collapsing following the building strike that killed the ten civilians. The warning, reported at 15:59 UTC on 28 May, represented a sharp deterioration in the diplomatic atmosphere surrounding the ceasefire framework that had been holding, albeit tenuously, in preceding weeks.

The ceasefire has been under strain for months. Periodic strikes by Israeli forces and exchanges of fire between the Israel Defense Forces and Palestinian armed groups have punctuated what was nominally a cessation of hostilities. Each incident has carried the risk of triggering a full breakdown, with mediators — primarily Qatar and Egypt, with involvement from the United States — working to prevent escalation. The deaths of civilian women and children in the 28 May building strike placed additional pressure on that diplomatic architecture, making the Hamas warning a predictable rather than surprising development.

The sources do not provide the specific terms of the ceasefire framework or the precise mechanism by which it could collapse. They also do not specify whether Hamas attributed the strike to a deliberate Israeli decision or to operational circumstances. What the reporting makes clear is that the civilian death toll has reintroduced a combustible element into negotiations that mediators had been working to stabilise.

The Problem of Civilian Harm in Urban Warfare

The deaths in Al-Zaytoun and the building strike in Gaza City raise the recurring problem of civilian harm in densely populated urban environments. The Al-Zaytoun neighbourhood is a residential area south of Gaza City proper, populated largely by families displaced from other parts of the Strip. Targeting civilians there — or in a building in Gaza City containing women and children — presents acute proportionality questions under the laws of armed conflict, a standard that applies regardless of the political context.

Israeli military spokespeople have not issued a statement on the 28 May strikes in the source material reviewed. Whether the strikes were directed at identified militants, at infrastructure associated with Hamas or Palestinian Islamic Jihad, or at broader patterns of activity — a method of strike authorisation that carries higher civilian harm risk — is not specified in the available reporting. The IDF has historically maintained that it takes extensive measures to minimise civilian casualties and that incidents of civilian harm are investigated. Whether that process has been initiated for the 28 May strikes is unknown from the current source material.

The question of urban strike methodology is not new to this conflict. The challenge of distinguishing between military and civilian targets in areas where Hamas operates from within residential infrastructure has been a persistent feature of the fighting since October 2023. What the 28 May deaths demonstrate is that the problem has not been resolved under the ceasefire, and that each incident restarts a debate about the adequacy of Israeli targeting protocols that the ceasefire was supposed to move beyond.

Regional and Diplomatic Stakes

The stakes of a ceasefire collapse extend well beyond Gaza City. A breakdown would immediately affect the hostages held in the Strip, whose release has been the central demand of both Israeli domestic politics and the negotiating framework. It would also affect the reconstruction process, which is heavily dependent on the ceasefire holding long enough for aid flows and infrastructure work to proceed at scale. And it would affect the broader regional trajectory — including normalisation talks between Israel and Saudi Arabia, which remain contingent on progress toward a Palestinian resolution.

Hamas's warning, in this context, is less a threat than a statement of operational fact: the ceasefire is under stress, the civilian deaths are providing political cover for hardliners on both sides, and the diplomatic space for mediators to work is narrowing. The sources do not indicate whether Qatar, Egypt, or the United States had responded to the warning as of 28 May. The reporting from Middle East Eye suggests the warning was issued in the hours following the building strike, leaving little time for a diplomatic response to have been formulated.

What is clear is that the ceasefire's survival depends on incidents like the ones on 28 May being contained rather than escalated. With civilian deaths now adding political weight to each side's grievances, that containment has become harder to achieve.
