Billions of dollars will be needed to rebuild Gaza after the war between Israel and the Palestinian group Hamas, according to assessments from the United Nations.

Israel and Hamas agreed to a deal to halt fighting in the enclave and swap Israeli hostages for Palestinian prisoners, an official briefed on the agreement said on Wednesday.

Here is a breakdown of the destruction in Gaza from the conflict prompted by the Oct. 7, 2023 attack on Israel by Hamas, which at the time ruled the Palestinian enclave.

HOW MANY CASUALTIES ARE THERE?

The Hamas attack on Israel killed 1,200 people, according to Israeli tallies. Israel's retaliation has killed more than 46,000 people, according to Gaza's health ministry.

HOW LONG WILL IT TAKE TO CLEAR THE RUBBLE?

The United Nations warned in October that removing 42 million tons of rubble left in the aftermath of Israel's bombardment could take years and cost $1.2 billion. A UN estimate from April 2024 suggested it would take 14 years to clear the rubble.

The debris is believed to be contaminated with asbestos, with some refugee camps struck during the war known to have been built with the material. The rubble also likely holds human remains. The Palestinian Ministry of Health estimated in May that 10,000 bodies were missing under the debris.

HOW MANY BUILDINGS HAVE BEEN DESTROYED?

Rebuilding Gaza's shattered homes will take at least until 2040, but could drag on for many decades, according to a UN report released last year.

Two-thirds of Gaza's pre-war structures - over 170,000 buildings - have been damaged or flattened, according to UN satellite data (UNOSAT) in December. That amounts to around 69% of the total structures of the Gaza Strip.

Within the count are a total of 245,123 housing units, according to an estimate from UNOSAT. Currently, over 1.8 million people are in need of emergency shelter in Gaza, the UN humanitarian office said.

WHAT IS THE INFRASTRUCTURE DAMAGE?

The estimated damage to infrastructure totaled $18.5 billion as of end-January 2024, affecting residential buildings, commerce, industry, and essential services such as education, health, and energy, a UN-World Bank report said.

An update by the UN humanitarian office this month showed that less than a quarter of the pre-war water supplies were available, while at least 68% of the road network has been damaged.

HOW WILL GAZA FEED ITSELF?

More than half of Gaza's agricultural land, crucial for feeding the war-ravaged territory's hungry population, has been degraded by conflict, satellite images analyzed by the United Nations show.

The data reveals a rise in the destruction of orchards, field crops and vegetables in the Palestinian enclave, where hunger is widespread after 15 months of Israeli bombardment.

The UN Food and Agriculture Organization said last year that 15,000 cattle, or over 95%, of the total had been slaughtered or died since the conflict began and nearly half the sheep.

WHAT ABOUT SCHOOLS, UNIVERSITIES, RELIGIOUS BUILDINGS?

Palestinian data shows that the conflict has led to the destruction of over 200 government facilities, 136 schools and universities, 823 mosques and three churches. Many hospitals have been damaged during the conflict, with only 17 out of 36 units partially functional as of January, the UN humanitarian office's report showed.

Amnesty International's Crisis Evidence Lab has highlighted the extent of destruction along Gaza's eastern boundary. As of May 2024, over 90% of the buildings in this area, including more than 3,500 structures, were either destroyed or severely damaged.

Guns may have fallen silent in Gaza, but for Mahmoud Abu Dalfa, the agony is not over. He is desperately searching for the bodies of his wife and five children trapped under the rubble of his house since the early months of the war.

Abu Dalfa's wife and children were among 35 of his extended family who were killed when an Israeli airstrike hit the building in Gaza City's Shejaia suburb in December 2023, he said. As bombs continued to fall, only three bodies were retrieved.

"My children are still under the rubble. I am trying to get them out... The civil defense came, they tried, but the destruction makes it difficult. We don't have the equipment here to extract martyrs. We need excavators and a lot of technical tools," Abu Dalfa told Reuters.

"My wife was killed along with all my five children - three daughters and two sons. I had triplets," he said.

Burials are usually carried out within a few hours of death in Muslim and Arab communities, and failure to retrieve bodies and ensure dignified burials is agonizing for bereaved families.

"I hope I can bring them out and make them a grave. That's all I want from this entire world. I don’t want them to build me a house or give me anything else. All I want is a grave for them - to get them out and make them a grave," said Abu Dalfa.

The Palestinian Civil Emergency Service and medical staff have recovered around 200 bodies since the ceasefire between Hamas and Israel came into effect on Sunday, halting a 15-month conflict that has killed more than 47,000 Gazans.

The war in Gaza was triggered when Palestinian Hamas fighters attacked southern Israel on Oct. 7, 2023, killing 1,200 people and taking about 250 as hostages, according to Israeli tallies. At least 94 of those hostages remain in Gaza.

Mahmoud Basal, the head of the service, said extraction operations have been challenged by the lack of earth-moving and heavy machinery, adding that Israel had destroyed several of their vehicles and killed at least 100 of their staff.

Basal estimates the bodies of around 10,000 Palestinians killed in the war are yet to be found and buried.

A UN damage assessment released this month showed that clearing over 50 million tons of rubble left in the aftermath of Israel's bombardment could take 21 years and cost up to $1.2 billion.

OPENING AID CROSSINGS

As hundreds of truckloads of aid flowed into Gaza since Sunday, officials from the Palestinian Authority, rivals to Hamas, held meetings with European officials to arrange to assume responsibilities at two vital crossing points with Egypt and Israel.

A Palestinian official familiar with the matter said Egypt sent bulldozers and some engineering vehicles to carry out repairs to the road on the Gaza side of the border that had been damaged by Israel's ground offensive.

Like Abu Dalfa, thousands of Gaza's 2.3 million residents are searching for the bodies of relatives either missing under the rubble or buried in mass graves during Israeli ground raids.

Rabah Abulias, a 68-year-old father who lost his son Ashraf in an Israeli attack, wants to give his son a proper grave.

"I know where Ashraf is buried, but his body is with dozens of others, there is no grave for him, there is no tomb stone that carries his name," he said via a chat app from Gaza City.

"I want to make him a grave, where I can visit him, talk to him and tell him I am sorry I wasn't there for him."
