JERUSALEM (AP) — Israeli forces in Gaza have killed the leader of Hamas Yahya Sinwara chief architect of last year’s attack on Israel that sparked the war, the military said Thursday. It appeared that troops had unknowingly encountered him in battle, only to discover that a body in the rubble was Israel’s most wanted man.

Israeli leaders celebrated his killing as a settlement of scores, just over a year after Hamas-led militants killed about 1,200 people and kidnapped 250 others in Israel. stunned the country. They also presented it as a turning point the campaign to destroy Hamasurging the group to surrender and release about 100 hostages still in Gaza.

“Hamas will no longer rule Gaza. This is the beginning of the day after Hamas,” Prime Minister Benjamin Netanyahu said.

US officials said so hopes for a ceasefire with Sinwar out of the picture. But eliminating him may not end the devastating warin which Israel has destroyed much of the Gaza Strip and killed more than 42,000 Palestinians. Gaza’s health ministry does not distinguish between civilians and fighters but says more than half of the dead were women and children.

Sinwar’s death is a crippling blow to Hamas, but the group, which receives support from Iran, has proven resilient to losses suffered by past leaders. There was no immediate confirmation from Hamas about Sinwar’s death.

Netanyahu has said that Israel will continue to fight until all hostages are freed, and that it will maintain control of Gaza long enough to ensure that Hamas does not rearm — an effective occupation that raises the possibility of months or even years of continued fighting.

Earlier this month, Israel opened a new front in its country war with Hezbollahstepping up bombings in Lebanon and launching a ground campaign against the Iranian-backed militia after a year of cross-border fire trading.

In his speech on Sinwar’s death, Netanyahu said: “Our war has not ended.”

President Joe Biden said Sinwar’s death opens the way for “a political settlement that offers a better future for both Israelis and Palestinians.” He said he would talk to Netanyahu “to discuss the path to bringing the hostages home to their families and ending this war once and for all.”

Sinwar has been the leader of Hamas in the Gaza Strip for years. He was elevated to the group’s top leadership position in July after his predecessor, Ismail Haniyeh, was killed in an apparent Israeli attack in the Iranian capital Tehran.

In recent months, Israel has done the same a series of tall figures eliminated of Hamas and Hezbollah with air strikes. Israel claims to have killed the head of Hamas’s military wing, Mohammed Deif, but the group claims he survived.

But in Sinwar’s case, troops found him by chance.

Israeli military spokesman Admiral Daniel Hagari said Israeli forces have identified three Hamas militants running from building to building in Gaza’s southernmost city of Rafah. The troops tried to shoot them before running into a building.

The Israeli army released a drone video showing Sinwar’s final moments: In a room destroyed by shelling, a man sat in a chair, his face covered with a cloth, possibly to hide his identity. The video showed the man throwing a stick at the drone with one injured hand.

The army then fired an additional shell at the building, causing it to collapse and killing Sinwar, Hagari said. He said Sinwar was found with a bulletproof vest, grenades and 40,000 shekels ($10,707).

Some of Sinwar’s DNA had previously been found in tunnels near where troops found the bodies of six hostages in late August, Hagari said. The military believes weeks of searches in the area prompted Sinwar to come out of hiding, he said.

Photos circulating online showed the body of a man resembling Sinwar with a gaping head wound, wearing a military-style vest, half-buried in the rubble of a destroyed building. The security official confirmed that the photos were taken at the scene by Israeli security officials. The official spoke on condition of anonymity because of the ongoing investigation.

The army said three militants were killed in the operation. According to police, one of them was confirmed to be Sinwar through dental records, fingerprints and DNA tests. Sinwar was imprisoned by Israel from the late 1980s until 2011, during which time he underwent treatment for brain cancer, leaving Israeli authorities with extensive medical records.

Israeli Defense Minister Yoav Gallant addressed Hamas fighters, saying it is “time to come out, release the hostages, raise your hands and surrender.”

Netanyahu said Israel has “settled the score” with the man behind the October 7 attack, and that “evil has suffered a severe blow.” But, he added, “the task ahead is not yet complete.”

He said that anyone in Hamas who surrendered weapons and helped return the hostages would be able to leave Gaza safely. About a third of the prisoners still in Gaza are believed to be dead.

Hundreds of people demonstrated in Tel Aviv on Thursday evening for the release of the hostages after news of Sinwar’s death emerged. Some carried signs reading “Sinwar’s end, end the war.”

Ifat Kalderon, whose cousin, Ofer Kalderon, is being held hostage in Gaza, said he was happy Sinwar was dead but “afraid for the 101 hostages. … They might kill them or do something because of Sinwar’s murder.

In the central Gaza town of Deir al-Balah, a Palestinian woman driven from her home in the north said she hoped Sinwar’s death would end Israel’s campaign. “What other goals do they have than that? Enough. We want to go back,” said the woman, Umm Mohammed.

Some praised Sinwar as a symbol of resistance to Israel’s decades-long occupation of Palestinians in the West Bank. Ahmed Hamdouna, who also fled his home in northern Gaza, said Hamas could replace him. “After the leader will come a thousand leaders. After the man there will come a thousand men,” he said.

For over a week. Israeli forces are waging a ground campaign in the Jabaliya refugee camp in northern Gaza, saying they are battling Hamas fighters who have regrouped there.

On Thursday, an Israeli attack hit a school housing displaced Palestinians in Jabaliya, killing at least 28 people, Gaza’s Health Ministry said. Fares Abu Hamza, head of the Health Ministry’s emergency unit in northern Gaza, said a woman and four children were among the dead.

The Israeli military said it targeted a Hamas and Islamic Jihad command center at the school. It included a list of about a dozen names of people it identified as militants who were present when the strike was called. It was not immediately possible to verify the names.

Israel has repeatedly hit tent camps and schools housing displaced people in Gaza. The Israeli army says it carries out precise attacks on militants and tries to prevent harm to civilians, but its strikes often kill women and children.
