DOHA/CAIRO/JERUSALEM – Israel airstrikes killed at least 70 people in Gaza overnight on Thursday, residents and authorities in the enclave said, hours after a ceasefire and hostage release deal was announced to bring an end to 15 months of war between Israel and Hamas.

The complex ceasefire accord emerged on Wednesday after mediation by Qatar, Egypt and the US to stop the war that has devastated the coastal territory and inflamed the Middle East.

The deal, scheduled to be implemented from Sunday, outlines a six-week initial ceasefire with the gradual withdrawal of Israeli forces from the Gaza Strip, where tens of thousands have been killed. Hostages taken by militant group Hamas, which controls the enclave, would be freed in exchange for Palestinian prisoners detained by Israel.

Israel's acceptance of the deal will not be official until it is approved by the country's security cabinet and government, and a vote was slated for Thursday, an Israeli official said.

However, Israeli Prime Minister Benjamin Netanyahu accused Hamas of making last-minute demands and going back on agreements.

"The Israeli cabinet will not convene until the mediators notify Israel that Hamas has accepted all elements of the agreement," a statement from Netanyahu's office said.

It was unclear what impact the latest delay will have on the deal.

Hamas is committed to the ceasefire agreement announced by mediators on Wednesday, senior group official Izzat el-Reshiq said on Thursday.

Hardliners in Netanyahu's government were still hoping to stop the deal, though a majority of ministers were still expected to back it.

Finance Minister Bezalel Smotrich said his party would only stay in the government if Israel resumes the war full force until Hamas is defeated. Far-right police minister Itamar Ben-Gvir has also threatened to quit the government if the ceasefire is approved.

Calls for faster implementation

Some Palestinians called for the deal to be implemented more quickly.

"We lose homes every hour. We demand for this joy not to go away, the joy that was drawn on our faces – don't waste it by delaying the implementation of the truce until Sunday," Gazan man Mahmoud Abu Wardeh said.

While people celebrated the pact in Gaza and Israel, Israel's military conducted more attacks, the civil emergency service and residents said.

Mahmoud Basal, the spokesperson for the Palestinian Civil Emergency Service, said in a statement that 71 Palestinians had been killed and at least 200 others wounded.

The Israeli military is looking into the reports, a military spokesperson said.

At a news conference in Doha, Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani said negotiators are working with Israel and Hamas on steps to implement the agreement.

"This deal will halt the fighting in Gaza, surge much-needed humanitarian assistance to Palestinian civilians, and reunite the hostages with their families after more than 15 months in captivity," US President Joe Biden said in Washington.

His successor, Donald Trump, takes office on Monday and claimed credit for the breakthrough in Gaza.

If successful, the ceasefire will halt fighting that has razed much of heavily urbanized Gaza, killed over 46,000 people, and displaced most of the tiny enclave's pre-war population of 2.3 million, according to Gaza authorities.

That in turn could defuse tensions across the wider Middle East, where the war has stoked conflict in the Israeli-occupied West Bank, Lebanon, Syria, Yemen and Iraq, and raised fears of all-out war between arch regional foes Israel and Iran.

With 98 Israeli hostages remaining in Gaza, phase one of the deal entails the release of 33 of them, including all women, children and men over 50.

Food lined up at Gaza borders

The agreement calls for a surge in humanitarian assistance to Gaza, and the UN and the International Committee of the Red Cross said they were preparing to scale up their aid operations.

Global reaction to the ceasefire was enthusiastic.

Israeli troops invaded Gaza after Hamas fighters burst into Israeli border-area communities on Oct 7, 2023, killing 1,200 soldiers and civilians and abducting over 250 hostages, according to Israeli tallies.

Negotiations on implementing the second phase of the deal will begin by the 16th day of phase one, and this stage was expected to include the release of all remaining hostages, a permanent ceasefire and the complete withdrawal of Israeli forces from Gaza.

The third stage is to address the return of all remaining dead bodies and the start of Gaza's reconstruction supervised by Egypt, Qatar and the United Nations.
