Three Years On: The Numbers Behind Gaza's Devastation

Three years have elapsed since Israel began its military campaign against Palestinians in Gaza, a conflict that has fundamentally reshaped the territory and its people. The assault was launched on October 7, 2023, following an attack on southern Israel by Hamas's armed wing, the Qassam Brigades, and other Palestinian factions. That initial attack resulted in the deaths of 1,139 people and the capture of roughly 240 hostages. Israel's response was a relentless bombing campaign that transformed a 16-year blockade into a complete stranglehold on the enclave. Although a "ceasefire" was declared on October 10, 2025, violence has persisted, with attacks and fatalities continuing to be reported.

The human cost of the conflict is staggering. According to figures from the Palestinian Ministry of Health, at least 74,000 Palestinians have been killed over the three-year period. Among the dead are at least 21,000 children. This toll equates to approximately one out of every 30 people in Gaza, or roughly 3 percent of the pre-war population. It is important to note that these figures only account for deaths recorded at hospitals or officially registered by authorities. The true number of fatalities is likely far higher, as thousands remain buried beneath rubble or are classified as missing, making an accurate count impossible.

The scale of injury is similarly overwhelming. More than 175,000 people have been wounded, which translates to about one in every 13 residents of Gaza. A conservative estimate from the World Health Organization suggests that roughly 24 percent of the injured have sustained life-changing wounds that will require long-term rehabilitation. A quarter of those with such injuries are children. Meanwhile, the few health facilities still operational are overwhelmed and operating on shrinking supplies, unable to meet the immense demand for care.

The "ceasefire" that took effect on October 10, 2025, has proven to be a ceasefire in name only. Since that date, Israel has violated the agreement with near-daily attacks, resulting in the deaths of more than 1,000 people. An Al Jazeera analysis found that Israel conducted attacks on 325 of the past 361 days, leaving only 36 days without reported attacks, deaths, or injuries. Despite this persistent violence, the United States continues to insist that the ceasefire remains intact.

Specific figures from the Palestinian Ministry of Health reveal that since the ceasefire began at noon on October 10, at least 1,460 Palestinians have been killed and 5,116 have been injured. These numbers underscore the gap between the diplomatic narrative of a halted conflict and the reality on the ground, where families continue to bury their dead and hospitals treat the wounded amid ongoing hostilities.

Gaza's healthcare infrastructure has been decimated. According to the UN Office for the Coordination of Humanitarian Affairs (OCHA), 94 percent of all hospitals and clinics are either fully or partially out of service. Only 42 of the territory's 666 healthcare facilities remain functional. This means that patients suffering from chronic illnesses, injuries, or preventable diseases are left without essential care. International humanitarian law, specifically the Fourth Geneva Convention, prohibits attacks on hospitals and grants special protection to medical units and personnel. Under the Rome Statute of the International Criminal Court, intentionally targeting a hospital constitutes a war crime. The near-total destruction of Gaza's medical system raises grave legal and moral questions.

Access to clean water has become a critical crisis. Since October 2023, Israel has systematically targeted Gaza's already fragile water infrastructure, striking wells, pipelines, desalination plants, and sewage systems. UN experts have stated that most of the water and sanitation network has been damaged or destroyed. Local authorities report that pipes and wells are either contaminated by sewage or cut off by fighting and displacement. As a result, 91 percent of households face water insecurity. Nearly half of Gaza's population now survives on less than six litres of water per day for drinking and cooking, far below the emergency minimum of 20 litres deemed necessary for short-term survival.

The destruction of homes and civilian infrastructure is near total. OCHA reports that 82 percent of all structures in Gaza have been destroyed. Entire neighbourhoods have been wiped out, displacing 1.98 million Palestinians—90 percent of the population. Newly updated Google Maps satellite imagery confirms the scale of the devastation across the besieged strip, showing a landscape of ruins where communities once stood. The displacement crisis has forced families into overcrowded shelters, makeshift tents, and the rubble of their former homes, with no clear path to rebuilding.

Gaza's education system has collapsed entirely. Approximately 93 percent of schools require complete reconstruction, according to OCHA, leaving more than 700,000 students without access to formal education. At least 63 university buildings have been destroyed, and those still standing are being used as shelters for displaced people. The loss of education represents a long-term blow to Gaza's future, depriving an entire generation of learning and the stability that schooling provides.

The cumulative effect of these figures paints a picture of a society pushed to the brink of annihilation. With one in 30 people killed, one in 13 injured, nearly all homes destroyed or damaged, and essential services like healthcare, water, and education in ruins, the very fabric of life in Gaza has been torn apart. The "ceasefire" has done little to stem the violence, and the international community remains divided on how to respond.

Legal experts and human rights organizations have pointed to the scale and systematic nature of the destruction as evidence of genocidal intent, a charge Israel denies. The targeting of hospitals, water infrastructure, and schools—all protected under international law—has drawn widespread condemnation. Yet, accountability remains elusive, and the suffering continues.

For the people of Gaza, the numbers are not abstractions. They represent lost children, shattered families, destroyed futures, and a daily struggle for survival. Three years after the conflict began, the territory remains a landscape of ruins, its population traumatized and displaced, with no end in sight to the crisis. The world watches, but for Gazans, the nightmare persists.
