Hamas leader Yahya Sinwar was killed by Israeli forces in Gaza.
Israeli authorities said they killed Hamas leader Yahya Sinwar, who has been credited as the mastermind behind the Oct. 7, 2023, attack on Israel.
The development comes as Israel continues intense air and ground campaigns against Hezbollah in Lebanon and against Hamas in the Gaza Strip.
The uptick in offensive operations came after Israel marked the anniversary of Hamas' Oct. 7 assault, and as Israeli leaders planned their response to Iran's latest ballistic missile attack.
Hamas political leader Yahya Sinwar was killed by Israeli forces on Thursday, Israel Foreign Minister Israel Katz confirmed in a statement.
"The master murderer Yahya Sinwar, who is responsible for the massacre and atrocities of October 7, was killed today by IDF soldiers," Katz said.

Egypt replaced the head of its general intelligence agency -- who played an instrumental role in brokering a Gaza cease-fire deal -- amid stalled negotiations. Deputy Hassan Rashad was named as new head of the agency.
Abbas Kamel, a longtime confidant and close aide to President Abdel Fattah al-Sisi, had headed the general intelligence agency since 2018 and was seen as the country’s second-most powerful figure.
Sisi relied heavily on Kamel for managing foreign policy affairs, including conflicts in Gaza and Sudan, as well as domestic security issues such as a wide-scale crackdown on dissent.
The change comes amid stalled negotiations for a cease-fire in the ongoing war in Gaza, which has spread into Lebanon. Kamel was a lead negotiator in the mediation efforts by Egypt, the U.S. and Qatar to end to the yearlong conflict. He played a key role in the diplomacy that led to a weeklong truce in November 2023.
Kamel will now take up a post of presidential adviser and envoy, as well as general coordinator of security services, according to a presidency statement.

The Israel Defense Forces are "checking the possibility" that Hamas leader Yahya Sinwar is one of the three militants it killed in Gaza on Thursday.
"At this stage, the identity of the terrorists cannot be confirmed," the IDF wrote in a post to X. "In the building where the terrorists were eliminated, there were no signs of the presence of hostages in the area. The forces that are operating in the area are continuing to operate with the required caution."
The 62-year-old has served as Hamas' leader in Gaza since 2017 and assumed leadership of the group's political bureau after the Israeli assassination of Ismail Haniyeh in Iran this July.

At least 28 people were killed and 160 others were wounded in an Israeli strike on the Abu Hussein School in northern Gaza where displaced people were sheltering, according to the Hamas-run Government Media Office.
In a statement, Hamas said Israel’s claims "that Abu Hussein School is being used for resistance purposes are mere lies, and it is a systematic policy of the enemy to justify its crime."
