Hamas leader Yahya Sinwar, the mastermind behind the Oct. 7, 2023, attack on Israel, was killed this week in a firefight with Israeli forces, officials said.
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 as Israeli leaders planned their response to Iran's latest ballistic missile attack.
87 killed in Israeli strikes on Beit Lahia, officials say
Israel killed 87 Palestinians in a Saturday night bombardment of Beit Lahia in northern Gaza, the Hamas-run government media office in the strip reported.
Around 40 people were injured in the attacks, with many others reported missing and believed to be under rubble, officials said. Aid teams were working to reach the victims, the office added.
The Israel Defense Forces issued a statement disputing the media office's report.
The IDF claimed in a post on X that the toll was "exaggerated" and does not align with its analysis.

WHO chief condemns latest attacks on Gaza hospitals
World Health Organization Director-General Tedros Adhanom Ghebreyesus reiterated calls for the protection of the few hospitals still operating inside Gaza on Saturday, following reports of fresh Israeli strikes on two health care facilities in the north of the strip.
"Hostilities in the vicinity of hospitals can quickly make them non-functional by compromising access," Ghebreyesus wrote on X. "We cannot request any more loudly: health care must be protected."
Ghebreyesus' latest appeal followed reported Israeli attacks on the Indonesian Hospital and Al-Awda Hospital in northern Gaza.
Both are in the Jabalia area in the north of the strip, which is the focus of a fresh Israeli offensive and a sweeping evacuation order for residents.
"We call for sustained and safe access to reach all patients and health workers in need," Ghebreyesus wrote. "We call for an immediate ceasefire!"

The WHO chief said the organization is "planning a mission to Kamal Adwan hospital" in Beit Lahia -- just north of Jabalia -- on Sunday "to deliver fuel, medical supplies, blood, food and transfer critical patients to Shifa hospital."
"It is vital that Kamal Adwan and Al-Awda hospitals remain operational," Ghebreyesus said.
Gaza's 36 hospitals and nine field hospitals have been badly affected by more than a year of war.
ABC News analysis found that as of Sept. 24, only four field hospitals were still functional, all in the central or southern areas of the strip. Twenty-two hospitals were partially functioning, with the remaining 19 non-functioning.
