The United Nations emphasized Thursday that the postwar reconstruction of Gaza would require an international effort unseen since the aftermath of World War II, estimating it could cost up to $40 billion.
Hamas chief Ismail Haniyeh struck an optimistic tone over a possible truce and hostage release deal for Gaza, after weeks of largely stalled negotiations.
Reports suggest ongoing sticking points between the Palestinian group and Israel nearly seven months into the devastating conflict.
But Haniyeh's Qatar-based political bureau said in calls to Egyptian and Qatari mediators that Hamas was studying the latest proposal with a "positive spirit."
Much of Gaza has been reduced to a gray landscape of rubble, and the United Nations estimated the cost of reconstruction at between $30 billion and $40 billion.
"The scale of the destruction is huge and unprecedented ... this is a mission that the global community has not dealt with since World War II," U.N. assistant secretary-general Abdallah al-Dardari told a briefing in the Jordanian capital Amman.
The U.N. official said, "(some) 72% of all residential buildings have been completely or partially destroyed."
Reconstruction is made more difficult by the presence of large quantities of unexploded ordnance in the debris that Gaza's Civil Defense agency says triggers "more than 10 explosions every week."
Israel's genocidal offensive against Hamas has killed at least 34,596 people in Gaza, mostly women and children, according to the Health Ministry, following Hamas's Oct. 7 incursion on Israel, which resulted in the deaths of 1,170 people, according to Israel.
Mediators have proposed a deal that would halt fighting for 40 days and exchange Israeli hostages for potentially thousands of Palestinian prisoners, according to details released by the U.K.
An Israeli official not authorized to speak publicly said Israel was still waiting for Hamas' formal response to the latest proposal.
Before Haniyeh's comments on Thursday, Hamas officials had given it a generally negative reception.
Senior Hamas official Osama Hamdan told Agence France-Presse (AFP) late Wednesday that the movement's position on the proposal was "negative" for the time being.
Another senior Hamas official, Suhail al-Hindi, said the group's aim remained an "end to this war" – a goal at odds with the stated position of Israeli Prime Minister Benjamin Netanyahu.
However, the resistance group has reportedly come under intense pressure from mediators to accept the latest offer.
"Hamas needs to say yes and needs to get this done," U.S. Secretary of State Antony Blinken said in Israel on Wednesday on his latest Middle East crisis tour.
Following talks with Blinken, Israeli opposition leader Yair Lapid said the prime minister "doesn't have any political excuse not to move to a deal for the release of the hostages."
Regardless of whether a truce is reached, Netanyahu has vowed to send Israeli ground troops into Rafah, despite U.S. opposition to any operation that fails to provide protection for the 1.5 million civilians sheltering in Gaza's southernmost city.
"We will do what is necessary to win and overcome our enemy, including in Rafah," he pledged at the start of a Cabinet meeting Thursday.
Separately, Netanyahu told a delegation of Holocaust survivors that Jews should welcome but not expect non-Jewish support and should be ready to "stand alone" if necessary.
"If it is possible to recruit 'Gentiles,' that's good. But if we don't protect ourselves, no one will protect us," he told the group at his office.
The prime minister faces regular protests calling on him to make a deal that would bring home the remaining captives.
On Thursday, protesters set up oversized photographs of women hostages outside Netanyahu's Jerusalem residence.
In Tel Aviv, they again blocked a highway.
Criticism of the war has also intensified in the U.S., Israel's top military supplier.
Demonstrations have spread to at least 30 U.S. universities, with some protesters erecting encampments to oppose Gaza's rising death toll.
Israeli President Isaac Herzog slammed the student protests, charging that U.S. universities had been "contaminated by hatred and anti-Semitism."
President Joe Biden said the U.S. was "not an authoritarian nation where we silence people" but added that anti-Semitism had "no place" on U.S. campuses.
In response to U.S. pressure, Israel has allowed increased aid deliveries into Gaza in recent days, including through a reopened crossing.
But U.N. aid chief Martin Griffiths said that "improvements in bringing more aid into Gaza" cannot be used "to prepare for or justify a full-blown military assault on Rafah."
At south Gaza's largest hospital, the Nasser Medical Complex in Khan Yunis, which was heavily damaged by Israeli attacks in February, foreign aid and borrowed equipment has helped to "almost completely" restore the emergency department, its director Atef al-Hout said.
Witnesses and an AFP correspondent reported Israeli airstrikes on Khan Yunis Thursday and shelling in the Rafah area.
In north Gaza, workers unloaded aid at Kamal Adwan Hospital where Alaa al-Nadi's son lay motionless in the intensive care unit, his head almost completely swathed in bandages.
Nadi, who was also wounded in the Israeli strike, said she feared the hospital's power might go out, cutting the boy's oxygen and killing him.
"I call on the world to transfer my son for treatment abroad. He is in a very bad condition," she said, breaking down in tears.
