Israelis mourn 7 October attack victims as Gaza lies in ruins three years on

What happened in Israel on 7 October, and why is the attack remembered as a national trauma?

On 7 October 2023, Hamas-led fighters and other armed groups crossed from Gaza into southern Israel. They attacked communities, a music festival, and military positions, killing about 1,200 people and taking 251 hostages, according to Israeli figures. The assault was sudden and widespread.

It is remembered as a national trauma because civilians were killed in their homes and communities were overrun. Many Israelis saw the attack as the country’s worst security failure in decades. The BBC reports that families still mourn victims and demand answers three years later. Hostage cases have kept the trauma present.

The consequences remain political as well as personal. Israelis are asking how warnings were missed and why the army responded slowly in some areas. The attack triggered the Gaza war and transformed Israeli politics. It also produced a lasting argument over security, leadership, accountability, and the country’s future relationship with Gaza.

What is Hamas, and what role did it play in the 7 October attack?

Hamas is a Palestinian Islamist movement founded during the first Palestinian uprising. It combines political activity, social services, and an armed wing. Hamas won Palestinian legislative elections in 2006 and seized control of Gaza in 2007 after fighting with Fatah. Several governments, including the United States, United Kingdom, and European Union, designate Hamas as a terrorist organization.

On 7 October 2023, Hamas’s armed forces led a coordinated assault from Gaza into Israel. Other armed groups also took part. The attackers breached the border, entered Israeli communities and military sites, killed civilians and soldiers, and seized hostages. The assault was therefore a Hamas-led operation, not an action by Gaza’s civilian population as a whole.

Hamas’s role drove Israel’s decision to launch a major military campaign in Gaza. It also shaped the hostage negotiations and Israel’s stated war aim of dismantling Hamas’s military and governing capacity. Hamas remained both an armed opponent and Gaza’s de facto authority, complicating questions about representation and civilian protection.

How many people were killed, injured, taken hostage, or displaced in the attack and the war that followed?

The clearest figures concern the attack itself. Israeli authorities report about 1,200 people killed, including civilians and security personnel, and 251 people taken hostage. Thousands were injured. Some early reports gave higher death estimates, so later official revisions matter. The headlines supplied here do not provide a single consolidated casualty table.

The war’s toll is much larger. By 2025, Gaza’s health authorities had reported more than 60,000 Palestinian deaths, while many more people were injured. Around 1.9 million people, or most of Gaza’s population, had been displaced at some point. Israel also evacuated or temporarily displaced large numbers of residents near Gaza and Lebanon.

These figures are difficult to verify during active fighting. They can change as bodies are identified, people remain missing, and indirect deaths are counted. The BBC and Guardian headlines focus on mourning, destruction, and displacement rather than one final total. Any comparison should state the date, source, and counting method.

How did the 7 October attack lead to the war in Gaza, and what has happened to Gaza as a result?

The attack directly triggered the war because Israel treated it as an armed assault requiring a large military response. Israel declared war, called up reservists, and began airstrikes before sending ground forces into Gaza. Its stated goals included returning hostages, defeating Hamas, and preventing another attack. Hamas continued firing rockets and holding hostages.

The campaign produced enormous destruction. Israeli operations struck homes, hospitals, schools, roads, and other sites, while fighting and evacuation orders pushed civilians from place to place. Restrictions on entry and movement also reduced access to food, water, fuel, medicine, and electricity. Hamas’s military presence in populated areas made combat especially dangerous for civilians, but did not remove Israel’s legal duties.

The Guardian and BBC describe Gaza as devastated and largely ruined after years of war. The future remains uncertain. Reconstruction will require security, funding, governance, and political agreement. The unresolved hostage issue, civilian suffering, and competing demands for accountability continue to obstruct any durable settlement.

Why are Israelis demanding accountability, and which institutions or leaders are being asked to explain the failures before the attack?

The accountability demand concerns how an attack of this scale became possible. Israelis want to know whether leaders ignored warnings, misread Hamas’s intentions, weakened preparedness, or failed to protect border communities. They also want a clear account of the delayed military response. This matters because public trust depends on learning whether failures were individual, institutional, or political.

The institutions under scrutiny include the Israel Defense Forces, military intelligence, the Shin Bet domestic security service, and the political leadership. Prime Minister Benjamin Netanyahu and his ministers face particular pressure because they set national policy and oversee security agencies. Families of victims and hostages have also demanded action and fuller information.

The BBC reports that Israelis are calling for accountability three years after the attack. A formal independent commission could examine warnings, decisions, command structures, and the response. Resignations may address political responsibility, but institutional reform would require changed procedures, oversight, and emergency readiness. Accountability remains contested while the war and hostage issue continue.

How does the Israeli-Palestinian conflict, including the blockade of Gaza and earlier wars, provide context for the events of 7 October?

The Israeli-Palestinian conflict has lasted for decades, involving competing national claims, occupation, settlements, displacement, and failed peace efforts. Israel withdrew its settlers and soldiers from Gaza in 2005, but Hamas took control in 2007. Israel, with Egypt’s cooperation, then imposed a blockade that restricted people and goods. Israel says the restrictions protect it from Hamas; Palestinians describe them as collective punishment.

Gaza also experienced major wars in 2008–09, 2014, and 2021, plus repeated smaller escalations. These conflicts created poverty, trauma, damaged infrastructure, and deep hostility. Hamas presented armed resistance as a response to this history. On 7 October, it crossed the border and attacked Israeli civilians and soldiers, turning a long conflict into a much wider war.

Context explains grievances and escalation, but it does not excuse deliberate attacks, hostage-taking, or unlawful harm. The blockade and earlier wars remain central to any solution. Without addressing security, Palestinian freedom and statehood, reconstruction, and governance, ceasefires are likely to remain fragile.

What rules does international humanitarian law set for protecting civilians and treating hostages and prisoners during war?

International humanitarian law sets limits on how wars are fought. The central rule is distinction: parties must target fighters and military objectives, not civilians or civilian objects. Attacks must be proportionate, meaning expected civilian harm cannot be excessive compared with the concrete military advantage. Commanders must take feasible precautions, and parties must allow and facilitate humanitarian relief.

The law absolutely prohibits hostage-taking, murder, torture, sexual violence, and humiliating or degrading treatment. Captured fighters must be treated humanely. Prisoners of war receive specific protections when that status applies. Civilians under an occupying power or military control remain protected. Hospitals and medical workers also receive special protection, although they can lose protection if used for harmful military acts, subject to strict rules.

These duties apply to Israel and Palestinian armed groups, including Hamas. Violations by one side do not cancel the other side’s obligations. Alleged breaches can be investigated by national authorities, international bodies, or courts. Protecting civilians and securing hostage releases are legal duties, not optional gestures.
