Killing of Yahya Sinwar

Overview

On October 16, 2024, soldiers of the Israel Defense Forces (IDF) killed Yahya Sinwar in Rafah, southern Gaza. Sinwar led Hamas, the terrorist organization responsible for the October 7 attacks on Israel. An IDF force from the 828th Brigade encountered three Hamas members during a ground operation. Infantry and armored units engaged them, killing all three. Soldiers recognized that one of the dead men resembled Sinwar; DNA testing and fingerprints confirmed his identity. Israeli officials announced the confirmation on October 17. [5][6][7]

The encounter formed part of the Gaza war (2023–present), which followed the Hamas-led assault of October 7, 2023. Sinwar had masterminded that attack. Hamas and its accomplices killed approximately 1,200 people, committed sexual violence, and took more than 250 hostages into Gaza. Sinwar’s death removed Hamas’s foremost leader and the central figure associated with the attack, but it did not end the war or secure the captives’ release. At the time of his death, Hamas still held 101 hostages, including seven Americans who were living or dead. [2][6][7][13]

The killing resulted from a patrol’s response to armed men, rather than a raid launched with advance knowledge of Sinwar’s location. Israeli intelligence and military operations had narrowed the areas in which senior Hamas figures could move. American Special Operations and intelligence personnel had worked with Israeli counterparts in the wider search for Sinwar and other Hamas leaders. United States forces did not participate in the encounter that killed him. [5][6][7][11]

Background

Sinwar was born on October 29, 1962, and grew up in Khan Yunis in Gaza. He belonged to a Muslim Brotherhood circle involved in creating Hamas as a Brotherhood affiliate in 1987. During the 1980s, he helped establish Al Majd, an internal security organization that sought suspected collaborators with Israel. He formed a lasting friendship in Khan Yunis with Mohammed Deif, who later became a senior commander of Hamas’s armed wing. Sinwar’s early work gave him influence within the organization’s security apparatus before he assumed its political leadership. [4]

Israeli authorities arrested Sinwar in 1988. He received four life sentences for terrorist activity against Israel and the murders of people suspected of collaborating with it. During his imprisonment, an Israeli hospital successfully treated him for a brain tumor. His incarceration made him a prominent figure in Hamas’s prisoner politics, and his eventual release became a defining episode in his rise. The United States placed him on its terrorism blacklist in 2015. [4][15]

In 2011, Israel released Sinwar through an exchange that returned abducted IDF soldier Gilad Shalit. Hamas had held Shalit for more than five years. Israel freed 1,027 prisoners in the exchange. Sinwar subsequently built influence among Hamas’s commanders in Gaza and pledged to use every measure to free Hamas prisoners from Israeli jails. The exchange linked his personal ascent to a method that remained central to Hamas’s strategy: holding Israelis captive to demand concessions and prisoner releases. [10][15]

Hamas violently seized power in Gaza in 2007. Sinwar became a senior Hamas military leader during the 2014 Gaza War. During ceasefire negotiations that year, he pressed the organization to demand further Israeli concessions before pausing combat. His position reflected a willingness to continue fighting in pursuit of Hamas’s demands. He was also implicated in the detention and torture of Hamas commander Mahmoud Ishtiwi, who was initially held on an embezzlement accusation in 2015 and subsequently killed following accusations of moral offenses within Hamas. These episodes formed part of Sinwar’s record of coercion within the organization as well as conflict with Israel. [4]

A secret Hamas election in February 2017 made Sinwar head of its operations in Gaza, replacing Ismail Haniyeh. His elevation strengthened the influence of commanders associated with the armed wing over Hamas’s leadership in Gaza. Sinwar remained closely identified with hostage taking and the demand for prisoner exchanges. After Haniyeh’s death in July 2024, Hamas elevated Sinwar to its overall leadership while he was hiding from Israeli forces. Its political leadership was based in Qatar, creating a divide between leaders abroad and commanders directing fighters in Gaza. [3][14][15]

Sinwar planned the October 7, 2023, attack on Israel. On the eve of the assault, Izz al-Din al-Haddad distributed operational instructions to Hamas commanders that included abducting Israeli soldiers. Haddad, like Sinwar, had served in Al Majd. The assault’s murders, sexual violence and mass abductions led Israel to launch military operations against Hamas in Gaza. The search for Sinwar then became a major objective within a wider campaign against Hamas’s command structure and military infrastructure. [1][5][6][13]

Course of the war

For a year after October 7, Sinwar evaded Israeli forces as operations proceeded through Gaza. The IDF and Israel’s internal security service searched areas associated with senior Hamas figures, using intelligence to guide forces in southern Gaza. The IDF’s Southern Command, 162nd Division and Gaza Division operated in areas where intelligence indicated that Hamas leaders might be hiding. American intelligence and special operations personnel assisted Israeli counterparts in efforts to locate and track Sinwar and other Hamas leaders; American personnel also supported the search for hostages. That cooperation formed part of the broader pursuit, while the final encounter was carried out by Israeli troops. [5][6][11][12]

Israeli forces pursued Sinwar through Hamas’s network of buildings and tunnels. Material recovered by the IDF showed that he had entered underground facilities around the start of the war. Operations in Khan Yunis pushed the search toward Rafah, where Hamas maintained tunnels used by senior members. Israeli forces found Sinwar’s DNA in a Rafah tunnel complex before his death, establishing that he had been there without fixing when he had used the site. The discovery was separate from the later DNA testing that identified his body. [8][13]

On October 16, a soldier of the 828th Brigade’s 450th Battalion noticed a suspicious figure moving near a building in Rafah’s Tel Sultan neighborhood. Later, a drone observed three armed men moving between buildings. Israeli troops engaged them. Two entered one building, while the third, subsequently identified as Sinwar, entered another. Armored units fired on the structures. Sinwar moved to an upper floor; as infantry approached, he threw grenades. A drone then entered the damaged building and filmed him with an injured arm and his face covered. He threw a wooden object toward the drone before further tank fire struck the building. [7][13]

The soldiers did not know during the exchange that they had encountered Hamas’s leader. Troops searching the building the next day saw that one of the dead men resembled Sinwar. Israeli authorities used DNA testing and fingerprints to verify his identity. The IDF and Israel’s internal security service confirmed his death on October 17. The brigade’s force had killed three Hamas members in the operation. Sinwar’s presence at the site turned an encounter with armed men into a major result of Israel’s campaign against Hamas’s leadership. [6][7]

Israel's conduct and the protection of civilians

Sinwar’s killing occurred during a ground encounter in a built-up area of Rafah. Infantry, armored vehicles and drones were used against the armed men and the buildings into which they had moved. The soldiers’ immediate decision concerned the threat they encountered; identification of Sinwar followed the fighting. IDF Chief of Staff Herzi Halevi said that troops had acted without advance intelligence that Sinwar was at that location. The operation therefore did not depend on treating everyone near a suspected leader as a target. [5][7]

Hostage safety was a pressing concern in operations involving Hamas leaders. Captives remained in Gaza, and Israeli forces had previously found evidence that Sinwar had used a Rafah tunnel complex near a separate passage where six hostages were murdered in August 2024. No hostages were found with Sinwar during the October 16 encounter. Israeli officials conveyed that finding to hostage families after his body was discovered. The absence of hostages at that scene did not resolve the danger faced by the 101 still held when his death was announced. [6][7][8]

The wider campaign also placed civilians in Gaza at risk as Israeli forces fought Hamas within populated areas. Hamas used civilians as human shields, while its leaders used tunnels and sites within civilian surroundings to sustain command and evade Israeli forces. These conditions made the distinction between armed members, captives and other people essential to the conduct of operations. In this encounter, Israeli forces engaged men they had identified during military activity and confirmed the identity of the most senior among them after the fighting ended. [2][6][7]

Terrorist tactics and propaganda

Hostage taking was central to the conflict that preceded Sinwar’s death. Hamas and its accomplices abducted more than 250 people in the October 7 attack, and their continued captivity gave Hamas a means of demanding a ceasefire and prisoner releases. Sinwar’s own release in the Shalit exchange showed the importance Hamas attached to that tactic. Haddad’s pre-attack instructions included the abduction of Israeli soldiers, placing hostage taking within the assault’s operational planning. The captives were people whose release remained an Israeli objective throughout the search for Sinwar. [1][6][10][13]

Hamas’s use of tunnels served both movement and concealment. Sinwar spent much of the war avoiding Israeli forces underground, and the IDF found evidence of his presence in a Rafah tunnel complex. He was killed only after moving above ground and encountering a patrol. The difference mattered to the public account of his death: images from his final moments circulated widely, while Israeli forces released material showing his earlier movement through tunnels. Claims drawn from isolated images could obscure the year-long pursuit, the ground encounter and the subsequent forensic identification. [7][8][13]

Sinwar’s record also shaped Hamas’s internal methods. Al Majd targeted suspected collaborators, and his involvement in the Ishtiwi affair showed the coercion used against members of the organization itself. Hamas’s propaganda presented its leaders as steadfast fighters, but Sinwar’s death did not demonstrate that he had directed the final encounter or chosen its timing. Israeli soldiers encountered three armed men without knowing that one was him. DNA evidence, fingerprints and the sequence recorded by troops and drones established the result of the operation. [4][7][13]

Outcome

Sinwar’s death removed the leader who had planned the October 7 attack and later headed Hamas as a whole. Israel regarded his killing as a major operational achievement in its campaign against the organization’s command and control. The result was specific: Sinwar and two other Hamas members died in the Rafah encounter. It was not the end of Hamas’s armed presence in Gaza. IDF leaders stated after the operation that Hamas retained the ability to threaten Israelis and that the mission to return the hostages continued. [5][6][7]

Prime Minister Benjamin Netanyahu told hostage holders after Sinwar’s death that those who laid down their weapons and released captives would be spared. He offered safe passage out of Gaza to anyone who released a hostage. He also pledged that Israel would continue working to bring the captives home. His offer joined an immediate incentive for release to the wider Israeli objective of ending Hamas’s rule in Gaza. At the time, 101 hostages remained in Hamas captivity, so Sinwar’s death created an opening rather than a completed hostage outcome. [6][9]

The killing disrupted Hamas’s leadership at a moment when hostage-for-ceasefire talks had been largely dormant since July 2024. Sinwar had combined authority over fighters in Gaza with the organization’s top political position. His removal changed the relationship between commanders on the ground and political figures based in Qatar. It also raised the prospect that negotiations could resume through leaders who had remained outside Gaza, although release of the hostages still depended on decisions by those controlling their captivity. [3][14]

Aftermath and legacy

After Sinwar’s death, his brother Mohammed Sinwar commanded Hamas fighters in southern Gaza, while Izz al-Din al-Haddad took command of its military forces in northern Gaza. Their regional commands meant that the loss of the overall leader did not eliminate Hamas’s capacity to direct armed activity. Haddad’s earlier role in Al Majd and his distribution of pre-October 7 instructions also connected the remaining command structure to the organization’s longstanding security methods and the attack that had precipitated the war. [1]

Political decision-making faced a separate transition. Former Hamas political chief Khaled Mashal became a key figure in discussions over the group’s direction, while Khalil al-Hayya remained its principal negotiator in hostage-for-ceasefire talks. Hamas’s Qatar-based leadership considered collective arrangements rather than immediately naming one successor to Sinwar. That shift reflected the practical difficulty of linking leaders abroad, commanders in Gaza and negotiations over people held captive. It did not change the fact that Hamas continued to hold hostages after the man who had planned their abduction was killed. [3][14]

United States Secretary of State Antony Blinken visited Israel after Sinwar’s death and held a two-and-a-half-hour meeting with Netanyahu. The visit focused attention on whether the change in Hamas’s leadership could advance a hostage agreement and reduce fighting. American intelligence and special operations cooperation had supported Israel’s wider search, but the United States military had no role in the October 16 encounter itself. The distinction between assistance in a prolonged pursuit and participation in the final operation remained important to understanding how Sinwar was found and killed. [3][11][12]

Sinwar’s death became a defining episode of the Gaza war because it joined several stages of the conflict in one event: his 2011 release through a hostage exchange, his ascent to Hamas leadership in 2017, his direction of the October 7 attack and Israel’s year-long pursuit. It also exposed the limits of removing one leader from an organization with dispersed commanders and hostages still in its hands. For Israel, the operation ended Sinwar’s leadership and delivered a major result against the architect of the October 7 attack. The immediate obligations that followed—securing the captives’ release and confronting Hamas’s remaining forces—continued after his death. [1][3][5][6][10]
