Israeli officials announced Thursday that Hamas leader Yayha Sinwar, the mastermind behind the group's Oct. 7 attack on Israel, had been killed by the Israeli Defense Forces.
Why it matters: Sinwar's death could make Israel more willing to scale back its operations in Gaza, Axios' Barak Ravid reports.
- The Oct. 7, 2023, assault by Hamas killed 1,200 people and saw 250 people taken hostage. Israel says 97 hostages remain captive in Gaza, some of whom may no longer be alive, per the Wall Street Journal.
- Israel has killed more than 42,000 Palestinians over the last year in the resulting war.
Driving the news: Sinwar was killed Wednesday night after IDF soldiers encountered three armed men during a routine patrol and exchanged fire with them.
- Israeli officials confirmed Thursday that one of the men was Sinwar.
- Hamas has not commented publicly on the reports of his death.
Sinwar's background
Sinwar was born in a refugee camp in Khan Younis, Gaza's second largest city, in 1962, according to AP.
- He became a member of Hamas' military wing at the time of its founding in 1987.
- He helped lead the group's counterintelligence arm before being convicted of killing four Palestinians accused of spying on Hamas for Israel in 1989.
- Sentenced to life in an Israeli prison, Sinwar became a leader among the Hamas prisoners in Israel and studied Hebrew and Israeli society. He was released after 22 years as part of a prisoner exchange.
- Upon his release, he resumed his role in the Hamas political and military apparatus, eventually becoming the group's leader in Gaza in 2017.
Leadership of Hamas
Sinwar became the head of Hamas' political bureau in August, following the assassination of his predecessor Ismail Haniyeh.
- Sinwar was previously the group's top official in Gaza but the move made him Hamas' top decision maker when it came to both Palestinian Territories and the diaspora.
- Israel's assassination of Haniyeh, his deputy Salah Arouri and the military commander Mohammed Deif left Sinwar as the Hamas' only remaining senior figure.
Sinwar's role in the Oct. 7 attack
Sinwar was one of the primary architects of the Oct. 7 attack on Israel, reportedly planning it with a small group of associates.
- Last month the Department of Justice charged Sinwar and other Hamas leaders with terrorism and a litany of other crimes related to the Oct 7 attack.
Zoom in: Following Oct. 7, 2023, Sinwar was believed to be hiding underground in Gaza's complex tunnel system.
- In February, the Israeli military consequently took control of much of the tunnel system in Khan Younis as part of its hunt for Sinwar and other Hamas leaders.
- Israeli and Arab officials confirmed last winter that Sinwar was in charge of Hamas' operations — including its participation in hostage negotiations — despite hiding in the tunnels, Axios' Barak Ravid reported.
