DOHA/CAIRO/JERUSALEM: Israel intensified strikes on Gaza hours after a ceasefire and hostage release deal was announced, residents and authorities in the Palestinian enclave said, as mediators sought to quell fighting ahead of the truce's start on Sunday.

The complex ceasefire accord between Israel and group Hamas, which controls Gaza, emerged on Wednesday after mediation by Qatar, Egypt and the U.S. and 15 months of bloodshed that devastated the coastal territory and inflamed the Middle East.

The deal 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 Hamas 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.

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 was 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.

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

On Thursday, Gaza forces fired a rocket into Israel, the Israeli military said, causing no casualties.

Israeli airstrikes throughout the night and early on Thursday killed at least 46 Palestinians, according to Gaza health officials.

At a news conference in Doha, Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani said the ceasefire would take effect on Sunday. Negotiators are working with Israel and Hamas on steps to implement the agreement, he said.

"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," U.S. President Joe Biden said in Washington.

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

Israelis will find it hard to see Palestinian forces who were serving life sentences for their involvement in deadly attacks in their country, set free.

But successive surveys have shown broad support among the public for a deal that would see the hostages released, even at what is seen as a heavy price.

"This has to be the only choice that we take in order to continue surviving as a state and as a nation, knowing that we will do anything to save each other," said Jerusalem resident Chava Treitel.

Israel secured major gains over Iran and its proxies, mainly Hezbollah, as the Gaza conflict spread. In Gaza, Hamas may have been crippled, but without an alternative administration in place it has been left standing.

JUBILATION IN GAZA

News of the ceasefire deal sparked jubilation in Gaza, where Palestinians have faced severe shortages of food, water, shelter and fuel. In Khan Younis, throngs clogged the streets amid the sounds of horns as they cheered, waved Palestinian flags and danced.

"I am happy. Yes, I am crying, but those are tears of joy," said Ghada, a displaced mother of five.

In Tel Aviv, families of Israeli hostages and their friends likewise welcomed the news, saying in a statement they felt "overwhelming joy and relief (about) the agreement to bring our loved ones home."

In a social media statement announcing the ceasefire, Hamas called the pact "an achievement for our people" and "a turning point."

If successful, the ceasefire will halt fighting that has razed much of heavily urbanised 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 THE GAZA'S BORDERS

The agreement calls for a surge in humanitarian assistance to Gaza, and the U.N. 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. Leaders and officials of Egypt, Turkey, Britain, the United Nations, the European Union, Jordan, Germany and the United Arab Emirates, among others, celebrated the news.

Biden and Trump both claimed credit for the deal that was months in the making but was helped across the line by a Trump emissary.

Israeli troops invaded Gaza after Hamas-led gunmen 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.

If all goes smoothly, the Palestinians, Arab states and Israel must still agree on a vision for post-war Gaza, including the unanswered question of who will run the enclave after the war.
