However, the Israeli military accused Hamas-affiliated organisations of "exaggerating" the number of dead, adding that the strike was directed at a Hamas target.

"This is a war of genocide and ethnic cleansing," the Hamas media office said. "The occupation has conducted a horrifying massacre in Beit Lahiya."

Health officials said ongoing rescue operations in Beit Lahiya were being hampered by the cut-off of telecommunication and internet services for a second day.

Earlier on Saturday, at least 35 people, including children, were killed in strikes across Gaza, according to the Gaza health ministry.

This includes a strike on the Maghazi refugee camp that killed 11 members of the same family, and another 10 who died when a house in the town of Zawayda was hit, according to the al Aqsa Martyrs Hospital in Deir al Balah.

It comes after a reported 33 people were killed in a strike on the Jabalia refugee camp late on Friday night, according to the Palestinian WAFA news agency.

More than 42,000 Palestinians have been killed and almost 100,000 others wounded during Israel's offensive in Gaza since 7 October 2023, according to Gaza's Hamas-run health ministry.

The health ministry does not differentiate between civilians and militants in its reporting of the figures.

Shockwaves from the killing of Hamas leader Yahya Sinwar continue to reverberate in the region, and speculation persists Israel could strike Iran's nuclear facilities.

Drone launched at Netanyahu's house

In Israel, a drone was launched towards the house of Israel's Prime Minister Benjamin Netanyahu, his spokesman said.

Prime Minister Sir Keir Starmer said he was "alarmed to hear" about the incident in a call to Mr Netanyahu on Saturday afternoon.

Sir Keir described Sinwar as a "brutal terrorist" and said the "world is a better place without him" as he discussed the situation in the Middle East with Mr Netanyahu.

"He also discussed with Prime Minister Netanyahu the opportunity presented by Sinwar's death to halt the fighting and get the hostages out," a spokesperson said.

"The prime minister also stressed the importance of getting much more aid into Gaza."

Sirens warned of incoming fire from Lebanon, with a drone launched towards a house owned by Prime Minister Netanyahu in Caesarea, the Israeli government said.

Neither Mr Netanyahu nor his wife were home at the time and there were no casualties, according to the Israeli leader's spokesperson.

In a statement on X, Mr Netanyahu said: "The agents of Iran who tried to assassinate me and my wife today made a bitter mistake.

"This will not deter me and the State of Israel from continuing the war of revival against our enemies to ensure our security for generations.

"Anyone who harms the citizens of the State of Israel will pay a heavy price for it."

The IDF said 55 projectiles were fired at northern Israel from Lebanon on Saturday morning, with some intercepted on route.

Deputy commander of Hezbollah killed

Israel also said on Saturday it killed Nasser Rashid in the town of Bint Jbeil in southern Lebanon.

The deputy commander of Hezbollah supervised attacks against Israel, the army said.

Khamenei: Hamas will live on

Iran's Supreme Leader Ayatollah Ali Khamenei has said the death of Hamas leader Sinwar will not halt the so-called "Axis of Resistance" and that Hamas would live on.

"His loss is undoubtedly painful for the Axis of Resistance, but this front did not cease advancing with the martyrdom of prominent figures," he said in a statement.

"Hamas is alive and will remain alive."

Meanwhile, a US defence official has told Sky News "we are looking into" reports of top secret documents containing intelligence on Israel's plan to attack Iran being leaked.

The documents are attributed to the US Geospatial Intelligence Agency and National Security Agency and note that "Israel continues to move military assets in place to conduct a military strike in response to Iran's blistering ballistic missile attack on 1 October", according to the Associated Press.
