"The mass murderer Yahya Sinwar, responsible for the massacre and atrocities of October 7th, was eliminated today by IDF (Israeli military) soldiers," Katz said in a statement sent to media.
Hamas leader Sinwar martyred

Israeli Foreign Minister Israel Katz on Thursday announced the killing of Hamas leader Yahya Sinwar, who Israel has accused of masterminding the group's attack on October 7 last year.
Israel accuses Sinwar of masterminding the attack, the deadliest in Israeli history, and has been hunting him down since the start of the Gaza war.
He became group's new leader after the killing of its former political chief Ismail Haniyeh in July.
Hamas and Iran blame Israel for Haniyeh's killing in an attack in Tehran, but Israel has not commented on it.
Israel's announcement on Sinwar comes weeks after it assassinated Hezbollah chief Hassan Nasrallah in a massive strike in Lebanon, where its military has escalated a war since late September.
A slew of other Iran-backed militant commanders have also been killed in recent months.
Israel said earlier this year that it had killed Mohammed Deif, Hamas's military chief, in a strike, though the Palestinian group has not confirmed it.
Deif stood accused of working with Sinwar to plan the October 7 attack.
With Hamas massively weakened more than a year into the Gaza war, Sinwar's death, if confirmed, would deal a seismic blow to the organisation.
In a brief statement, the military said that during "operations in the Gaza Strip, three terrorists were eliminated".
Israeli defence agencies "are checking the possibility that one of the terrorists was Yahya Sinwar. At this stage, the identity of the terrorists cannot be confirmed," the statement added.
An Israeli security official told AFP that the military was conducting a DNA test on a militant's body to confirm whether it was Sinwar's.
Israel's Defence Minister Yoav Gallant said the country would hunt down "every terrorist", following the military's announcement on Sinwar.
"We will reach every terrorist and eliminate them," Gallant wrote on X.
- Hamas weakened, not crushed -
Israel has been at war with Hamas since the October 7 attack, which resulted in the deaths of 1,206 people, mostly civilians, according to an AFP tally of official Israeli figures.
Israel's retaliatory campaign in Gaza has killed 42,438 people, the majority civilians, according to data from the health ministry in the Hamas-run territory, which the UN considers reliable.
Following the October 7 attack, Prime Minister Benjamin Netanyahu vowed to crush Hamas and to bring home all 251 hostages seized by militants in their cross-border onslaught.
Israel has since expanded the scope of its operations to Lebanon, where Hamas ally Hezbollah opened a front against Israel by launching low-intensity cross-border strikes that forced tens of thousands of Israelis to flee their homes.
Netanyahu has vowed to battle Hezbollah until victory, and Israel on Thursday launched strikes on the south Lebanese city of Tyre, where the militant group and its allies hold sway.
Israel also issued evacuation warnings for civilians in parts of Lebanon's eastern Bekaa Valley, a Hezbollah stronghold.
It had earlier struck a Hezbollah target in Syria, according to a war monitor, while Israel's main ally the United States used heavy bombers to hit rebel targets in Yemen.
Syria, the Huthi rebels in Yemen, Hezbollah in Lebanon and Hamas in Gaza all belong to the "axis of resistance" of groups aligned with Iran.
Tehran on October 1 conducted a missile strike on Israel, over which Israel has vowed to retaliate, sparking concern around the world that what is already a war on multiple fronts could morph into an all-out regional conflict.
- Iran warning -
Iran's Revolutionary Guards chief Hossein Salami on Thursday warned Tehran would hit Israel "painfully" if it attacks Iranian targets.
The Syrian Observatory for Human Rights, a Britain-based monitor, said the Israeli raid on the Syrian city of Latakia targeted a "weapons depot belonging to Hezbollah".
The Israeli military did not comment on the strike when contacted by AFP.
Israel has conducted hundreds of strikes in Syria in recent years, including multiple recent attacks along the Lebanese border that seek to cut off Hezbollah's main weapons and equipment supply route from Iran to Lebanon.
In Huthi-controlled areas of Yemen, the United States conducted multiple B-2 bomber strikes on weapon storage facilities, according to the US military and defence department.
The Huthis' political bureau said "the American aggression will not pass without a response", and vowed to continue the group's "support and assistance to Gaza and Lebanon".
The war in Lebanon has left at least 1,373 people dead, according to an AFP tally of Lebanese health ministry figures, though the real toll is likely higher.
Israeli troops and Hezbollah fighters have been clashing near Lebanon's southern border, where Hezbollah on Thursday said it hit four Israeli tanks with guided missiles.
Rescue workers affiliated with the Amal party, a Hezbollah ally, in the southern city of Qana were digging through the rubble of several buildings destroyed in strikes this week.
"More than 15 buildings have been completely destroyed, total destruction in a neighbourhood in Qana," said Mohammed Nasrallah Ibrahim, one of the rescuers.
Israel has faced criticism over its strikes in Lebanon, including from its tops arms supplier the US.
- Hunger in Gaza -
In northern Gaza's Jabalia, where almost the entire population is displaced, two hospitals said Israeli air strikes on a school sheltering displaced people killed at least 14 people.
The military reported that it had hit militants.
Some 345,000 Gazans face "catastrophic" levels of hunger this winter after aid deliveries fell, a UN-backed assessment said Thursday, warning of the persistent risk of famine.
Nearly 100 percent of Gaza's population now lives in poverty, with a "staggering" unemployment rate of nearly 80 percent, the UN's International Labour Organization said on Thursday.
The impact of the war on Gaza "will be felt for generations to come," said the ILO's Ruba Jaradat.
