Israel marks three years since Hamas-led 7 October 2023 attacks

What happened in the Hamas-led attacks on Israel on 7 October 2023?

On 7 October 2023, Hamas-led fighters launched a surprise assault from Gaza into southern Israel. They fired thousands of rockets, breached the border, attacked Israeli communities and military sites, and killed civilians and soldiers. The assault shocked Israel because the border had appeared heavily fortified.

The attackers also reached the Nova music festival near Re’im. Israeli authorities say about 1,200 people were killed, including civilians and security personnel, and 251 people were taken hostage. Thousands more were wounded. Hamas and other armed groups carried many hostages back into Gaza, creating a crisis that shaped Israel’s response.

The supplied source headlines focus on remembrance three years later, rather than providing a full incident-by-incident account. The attacks remain central to Israeli politics, public memory, and debates about security failures. They also triggered the prolonged Gaza war, whose human and political consequences continue to shape the region.

What is Hamas, and what role does it play in Palestinian politics and armed conflict?

Hamas is a Palestinian Islamist movement founded during the first intifada in 1987. It has a political organization and an armed wing, the Izz al-Din al-Qassam Brigades. Hamas rejects Israel’s legitimacy in its founding charter, though its political positions and documents have changed over time. Several governments, including Britain, the United States, and the European Union, designate Hamas as a terrorist organization.

Hamas won the 2006 Palestinian legislative election. In 2007, it seized control of Gaza after fighting forces loyal to President Mahmoud Abbas and his Fatah movement. Since then, Hamas has run Gaza’s internal administration while maintaining its armed capacity. It has fought repeated wars and exchanges of fire with Israel.

This dual role makes Hamas central to both Palestinian politics and armed conflict. It is a governing authority in Gaza, but not the internationally recognized Palestinian government. Its attacks, including 7 October, have brought severe Israeli military responses and deepened Palestinian political division.

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

The clearest figures concern the initial attack: Israeli authorities say about 1,200 people were killed, and 251 hostages were taken into Gaza. Thousands were wounded. These figures include civilians and security personnel, and the death toll was revised after victims were identified. Some hostages were later released, rescued, or confirmed dead.

The war that followed produced a far larger humanitarian toll. Gaza’s Health Ministry reported more than 67,000 Palestinian deaths by October 2025, while United Nations and health agencies reported well over 170,000 injuries. Around 1.9 million people, or roughly nine in ten Gazans, were displaced at some point, often repeatedly. Gaza authorities do not distinguish consistently between fighters and civilians.

Numbers remain contested and change as bodies are identified and records are updated. The supplied source headlines describe the three-year anniversary but give no current totals. Any figure should therefore include its date, source, and limits rather than suggest a final accounting.

Why is Israel commemorating the attacks, and why has the anniversary become politically important for Benjamin Netanyahu?

Israel marks 7 October as a national tragedy. Families remember relatives killed or abducted, communities mourn destroyed homes, and the country recalls the collapse of its security system. Memorial events also reflect the continuing trauma of the attacks. The supplied headlines describe Israeli remembrance and a London vigil, showing that commemoration extends beyond Israel.

For Benjamin Netanyahu, the anniversary carries an added political burden. He was prime minister when the attack occurred, so critics connect him to failures in intelligence, preparedness, and crisis management. Supporters argue that his government must continue the war until Hamas is weakened and hostages are returned. The anniversary therefore highlights competing demands for security, accountability, and a ceasefire.

The source says a crucial election looms, but it gives no date or polling detail. As a result, the anniversary can function as a political dividing line. Voters may judge Netanyahu’s leadership, the war’s results, hostage policy, and plans for Gaza’s future.

How did the 7 October attacks lead to Israel's military campaign in Gaza, and what consequences has that campaign had for people there?

After 7 October, Israel declared war and said its goals were destroying Hamas’s military and governing capacity, returning hostages, and preventing another attack. It launched intensive airstrikes, imposed or tightened restrictions on supplies, and later sent ground forces into Gaza. Israel says Hamas operates among civilians and uses tunnels and civilian buildings, making military operations difficult.

The campaign began with evacuation orders and bombardment, followed by ground fighting. Gaza’s population was pushed toward the south and later displaced again as front lines moved. Israeli attacks damaged homes, hospitals, schools, roads, water systems, and much of Gaza’s civilian infrastructure. Hamas continued firing rockets and holding hostages during the war.

The consequences include tens of thousands of Palestinian deaths, mass injuries, hunger, disease risks, and repeated displacement. Israel says military pressure is necessary for security; critics, including the Al Jazeera headline’s characterization, describe the campaign as genocidal, a charge Israel rejects and courts have not finally resolved. Gaza’s future governance remains uncertain.

How have the roles of Israel, Hamas, the Palestinian Authority, and Gaza changed or interacted since 2007?

The Palestinian Authority was created through the Oslo process and became the main Palestinian governing institution in parts of the West Bank. Israel retained broad security powers across much of that territory. Hamas won the 2006 legislative election, then fought Fatah forces and took Gaza in 2007. The split left two rival Palestinian centers of power.

Since then, Hamas has administered Gaza and maintained an armed wing. Israel and Egypt imposed varying degrees of blockade and access restrictions, while Israel and Hamas fought repeated conflicts. Israel withdrew its settlers and permanent ground forces from Gaza in 2005, but continued controlling or strongly affecting airspace, waters, crossings, population records, and movement. Egypt controls its own border crossing policy.

The Palestinian Authority has lacked control over Gaza and limited authority in the West Bank. The 7 October attack and Israel’s response further weakened prospects for unity. Any lasting settlement must address Gaza’s governance, Israeli security, Palestinian representation, reconstruction, and the unresolved division between Hamas and the Authority.

How do competing claims to land, security, sovereignty, and Palestinian self-determination make the Israeli-Palestinian conflict so difficult to resolve?

At its core, the conflict involves competing national claims to the same territory. Many Israelis seek a secure Jewish state and fear attacks, expulsion, or another massacre. Palestinians seek an independent state, equal rights, an end to occupation and blockade, and recognition of their national identity. Refugees, settlements, Jerusalem, borders, and control of resources add further disputes.

The 7 October attacks strengthened Israeli arguments that armed groups must be defeated and security control must remain strong. Israel’s Gaza campaign, occupation-related policies, and civilian losses strengthened Palestinian demands for self-determination and protection. Hamas rejects Israel’s political order and uses armed force, while Israel rejects Hamas as a security threat. The Palestinian Authority supports diplomacy but lacks authority in Gaza.

These positions interact in a cycle: violence produces fear, military control produces anger, and failed negotiations reduce trust. The source headlines show remembrance, mourning, and political pressure three years later, not a settlement. Progress would require credible security, legitimate Palestinian representation, territorial and political compromise, and accountability for abuses.
