Impact of Sinwar’s Death on Hamas and the Gaza War

No one in Israel or Palestine expected the Israeli army to kill Hamas leader Yahya Sinwar in what is described as an “accidental” strike, according to Israel’s account since Oct.7.

Israel officially announced Sinwar’s death in an strike on a house in Rafah, southern Gaza, just hours after the army began investigating whether he had been killed. Israeli Foreign Minister Israel Katz called it a “major victory.”

Since Sinwar orchestrated Hamas’ “Al-Aqsa Flood” attack in October last year, he has become Israel’s top target.

Prime Minister Benjamin Netanyahu, Defense Minister Yoav Gallant, and Chief of Staff Herzi Halevi had vowed to kill him, using military and intelligence resources, along with US and Western support, to make his death a key war objective.

Turning Point

The war has reached a significant “turning point” with the killing of Sinwar, which may allow Israel to end the conflict. This development could also give Hamas more flexibility after losing its hardline leader, who has reshaped the group in recent years.

Before Israel confirmed Sinwar’s death, Gallant, Halevi, and Shin Bet Director Ronen Bar visited the Gaza border for a security assessment. They also briefed US President Joe Biden about the situation.

Political analyst Mustafa Ibrahim told Asharq Al-Awsat that Sinwar’s assassination will have major impacts on future events.

A Hamas source described the news as a “shock.”

Following confirmation of Sinwar’s death, the source said Hamas leaders began discussions about their future, including the selection of a new leader, current confrontations, and ceasefire negotiations.

Sources familiar with Hamas’ decision-making suggest that Sinwar’s absence will shift control back to the leadership outside Gaza. This change could make negotiations for a ceasefire easier and quicker, which may align with Israeli interests.

Israeli public broadcaster Kan reported that urgent discussions occurred between the negotiation team and security officials following Sinwar’s killing.

Sinwar was among those released in the 2011 prisoner exchange between Hamas and Israel.

After his release, he quickly rose to power and was first elected head of Hamas in Gaza in 2017, succeeding Ismail Haniyeh, who then became the overall leader of the movement. Sinwar took over the leadership role in August.

Radical Control

One key change Sinwar made in Hamas was a “firmness of leadership,” according to a source close to the group. The source explained that Sinwar was a strong leader who made significant decisions about who would rise or fall within the organization.

He successfully pushed the military faction's agenda and took firm control of decision-making, even when communication with him became difficult for a time.

Most of Hamas’ leadership abroad, including members from Gaza and the West Bank, participated in crucial meetings and unanimously approved Sinwar as the leader without any competition.

Sinwar’s selection highlights the continued control of Gaza’s leadership within Hamas for the second consecutive term. This leadership, which includes Ismail Haniyeh and now Sinwar, has worked to align Hamas with the Iranian-led axis, according to analysts.

Comprehensive Review

A source close to Hamas told Asharq Al-Awsat that the movement has been significantly weakened by the loss of many of its hardline leaders. He suggested that Hamas is likely to conduct a thorough review of its policies, though a complete change is not guaranteed.

Regarding potential impacts, the source noted several key points: first, decision-making may shift back to leaders abroad, leading to significant changes; second, Hamas may have to make concessions that were difficult under Sinwar’s leadership, especially concerning the conflict, prisoner exchanges, and relations with the Palestinian Authority; and third, Hamas will seek to navigate current challenges, requiring extensive discussions.

The assassination of Sinwar is another setback for Hamas, which is already facing multiple difficulties.

Hamas leader Yahya Sinwar, a mastermind of the Oct. 7, 2023 attack on Israel that triggered the war in Gaza, has been killed in a military operation.
His death would be a significant moment in Israel's yearlong offensive against the militant group and could complicate efforts to release dozens of hostages held in Gaza.
Sinwar became the head of Hamas after the killing of the previous leader, Ismail Haniyeh, in an explosion in Iran in July that was widely blamed on Israel.
Some things to know about Sinwar:
From refugee camp to Hamas militant Sinwar was born in 1962 in a refugee camp in the Gaza town of Khan Younis. He was an early member of Hamas, which was formed in 1987. He eventually led the group's security arm, which worked to purge it of informants for Israel.
Israel arrested him in the late 1980s and he admitted to killing 12 suspected collaborators, a role that earned him the nickname “The Butcher of Khan Younis.” He was sentenced to four life terms for offenses that included the killing of two Israeli soldiers, The Associated Press reported.
A prison leader Sinwar organized strikes in prison to improve working conditions. He also studied Hebrew and Israeli society.
He survived brain cancer in 2008 after being treated by Israeli doctors.
Sinwar was among more than 1,000 Palestinian prisoners released in 2011 by Prime Minister Benjamin Netanyahu as part of an exchange for an Israeli soldier captured by Hamas in a cross-border raid.
When Sinwar returned to Gaza, he quickly rose through Hamas' leadership ranks with a reputation for ruthlessness. He is widely believed to be behind the 2016 killing of another top Hamas commander, Mahmoud Ishtewi, in an internal power struggle.
Sinwar became head of Hamas in Gaza, effectively putting him in control of the territory, and worked with Haniyeh to align the group with Iran and its proxies around the region while also building the group's military capabilities.
There is widespread evidence that Sinwar, along with Mohammed Deif, the head of Hamas’ armed wing, engineered the surprise Oct. 7 attack on Israel.
The International Criminal Court’s prosecutor sought arrest warrants in May for Sinwar, Deif and Haniyeh for their alleged roles in the attack.
Israel said it killed Deif in a strike in July, while Hamas says he is still alive.
Where would this leave Hamas? Sinwar has been in hiding since the attack, and cease-fire negotiators have said it can take several days to send and receive messages from him.
Even before becoming Hamas' top leader, Sinwar was believed to have the final word on any deal to release hostages held by the militant group. Some 100 hostages remain in Gaza, around a third of whom are believed to be dead.
It's unclear who would replace Sinwar, and what that might mean for the cease-fire efforts, which sputtered to a halt in August after months of negotiations brokered by the United States, Egypt and Qatar.
