A huge Soviet-era dam on the Dnipro River that separates Russian and Ukrainian forces in southern Ukraine was breached on Tuesday, unleashing floodwaters across the war zone.

Ukraine said Russia had destroyed it, while Russia said Ukraine sabotaged it to cut off water supplies to Crimea and distract attention from a "faltering" counter-offensive.

What is the dam, what happened - and what do we not know?

The Kakhovka dam

The dam, part of the Kakhovka hydroelectric power plant, is 30 meters (98 feet) tall and 3.2 km (2 miles) long. Construction was started under Soviet leader Josef Stalin and finished under Nikita Khrushchev.

The dam bridged the Dnipro river, which forms the front line between Russian and Ukrainian forces in the south of Ukraine.

Creation of the 2,155 sq km (832 sq mile) Kakhovka reservoir in Soviet times forced around 37,000 people to be moved from their homes.

The reservoir holds 18 cubic kilometers (4.3 cubic miles) of water - a volume roughly equal to the Great Salt Lake in the US state of Utah.

The reservoir also supplies water to the Crimean peninsula, which Russia annexed in 2014, and to the Zaporizhzhia nuclear plant, which is also under Russian control.

What happened?

Ukraine, which commented first, said Russia was responsible.

Ukrainian President Volodymyr Zelenskiy accused Russian forces of blowing up the Kakhovka Hydroelectric Power Station from inside the facility, and said Russia must be held to account for a "terrorist attack".

"At 02:50, Russian terrorists carried out an internal detonation of the structures of the Kakhovskaya HPP. About 80 settlements are in the zone of flooding," Zelenskiy said after an emergency meeting of senior officials.

A Ukrainian military spokesperson said Russia's aim was to prevent Ukrainian troops crossing the Dnipro River to attack Russian occupying forces.

Russia said Ukraine sabotaged the dam to cut off water supplies to Crimea and to distract attention from its faltering counteroffensive.

"We can state unequivocally that we are talking about deliberate sabotage by the Ukrainian side," Kremlin Spokesman Peskov told reporters.

Earlier some Russian-installed officials said no attack had taken place. Vladimir Rogov, a Russian installed official in Zaporizhzhia, said the dam collapsed due to earlier damage and the pressure of the water. Russia's state news agency TASS carried a report to the same effect.

What is the human impact?

With water levels surging higher, many thousands of people are likely to be affected. Evacuations of civilians began on both sides of the front line.

Some 22,000 people living across 14 settlements in Ukraine's southern Kherson region are at risk of flooding, Russian installed officials said. They told people to be ready to evacuate.

Ukrainian Prime Minister Denys Shmyhal said that up to 80 settlements were at risk of flooding.

Crimea

The destruction of the dam risks lowering the water level of the Soviet-era North Crimean Canal, which has traditionally supplied Crimea with 85% of its water needs.

Most of that water is used for agriculture, some for the Black Sea peninsula's industries, and around one fifth for drinking water and other public needs.

Nuclear plant

The Zaporizhzhia Nuclear Power Plant, Europe's largest, gets its cooling water from the reservoir. It is located on the southern side, now under Russian control.

"Our current assessment is that there is no immediate risk to the safety of the plant," International Atomic Energy Agency chief Rafael Grossi said.

He said it was essential that a cooling pond be left intact as it supplied enough water for the cooling of the shut-down reactors.

"Nothing must be done to potentially undermine its integrity," Grossi said.

Gaza Is in Ruins after Israel’s Yearlong Offensive. Rebuilding May Take Decades

The Gaza Strip is in ruins.

There are hills of rubble where apartment blocks stood, and pools of sewage-tainted water spreading disease. City streets have been churned into dirt canyons and, in many places, the air is filled with the stench of unrecovered corpses.

Israel’s yearlong offensive against Hamas, one of the deadliest and most destructive in recent history, has killed more than 41,000 people, a little over half of them women and children, according to local health officials. With no end in sight to the war and no plan for the day after, it is impossible to say when – or even if – anything will be rebuilt.

Even after the fighting stops, hundreds of thousands of people could be stuck living in squalid tent camps for years. Experts say reconstruction could take decades.

“This war is destruction and misery. It would make the stones cry out,” said Shifaa Hejjo, a 60-year-old housewife living in a tent pitched on land where her home once stood. “Whoever sees Gaza ... It will make them cry.”

Israel blames the destruction on Hamas. Its Oct. 7 attack on Israel — in which some 1,200 people were killed and around 250 taken hostage — ignited the war. Israel says Hamas embedded much of its military infrastructure, including hundreds of kilometers (miles) of tunnels, in densely populated areas where some of the heaviest battles were fought.

The fighting left roughly a quarter of all structures in Gaza destroyed or severely damaged, according to a UN assessment in September based on satellite footage. It said around 66% of structures, including more than 227,000 housing units, had sustained at least some damage.

If there's a ceasefire, around half of all families “have nowhere to go back to,” said Alison Ely, a Gaza-based coordinator with the Shelter Cluster, an international coalition of aid providers led by the Norwegian Refugee Council.

The devastation in Gaza rivals front-line towns in Ukraine

Almost as many buildings have been destroyed or damaged in Gaza as in all of Ukraine after its first two years of war with Russia, according to Corey Scher and Jamon Van Den Hoek, US-based researchers who use satellite radar to document the wars' devastation.

To put that into perspective: Gaza is less than half the size of Ukraine's capital, Kyiv.

The amount of destruction in central and southern Gaza alone, Scher said, is roughly equivalent to what was lost in the front-line town of Bakhmut, the scene of one of the deadliest battles in the Ukraine war and where Russian forces destroyed nearly every building in their path to force Ukrainian troops to withdraw. The destruction in northern Gaza is even worse, he said.

Gaza’s water and sanitation system has collapsed. More than 80% of its health facilities — and even more of its roads — are damaged or destroyed.

“I can’t think of any parallel, in terms of the severity of damage, for an enclave or a country or a people,” Scher said.

At the end of January, the World Bank estimated $18.5 billion of damage — nearly the combined economic output of the West Bank and Gaza in 2022. That was before some intensely destructive Israeli ground operations, including in the southern border city of Rafah.

’I couldn’t tell where people’s homes were’ When Israeli ground forces pushed into the southern city of Khan Younis in January, Shifaa Hejjo and her family fled their four-story home with only the clothes they were wearing.

They spent months in various tent camps before she decided to return – and the sight brought her to tears.

Her entire neighborhood had been destroyed, her former home and the roads leading to it lost in a sea of rubble.

“I didn’t recognize it,” she said. “I couldn’t tell where people’s homes were.”

Around 90% of Gaza’s 2.3 million people have been displaced by the war, often multiple times, according to UN estimates. Hundreds of thousands have crowded into sprawling tent camps near the coast with no electricity, running water or toilets. Hunger is widespread.

Hejjo lived in a tent in the courtyard of a hospital. Before that, she was in Muwasi, the main tent camp in southern Gaza.

“It smelled bad,” she said. “There were diseases spreading.”

She said her husband, who was suffering from liver disease, was broken-hearted when he heard their home had been destroyed and he died shortly thereafter.

She was among the first to return after Israeli forces withdrew in April. Her neighbors stayed away, fearful they would find bodies or unexploded bombs.

But for her it was still home.

“It is better to live in my home, where I lived for 37 years, even though it is destroyed,” she said.

Hejjo and her children dug through the rubble with shovels and their bare hands, going brick by brick and saving whatever could be reused. Torn clothes were used to feed cooking fires.

Rats had crept in, and swarms of mosquitoes hovered over the ruins. There was broken glass everywhere. They set up a tent fortified by corrugated metal sheeting and some bricks salvaged from her destroyed home. A light drizzle wet their clothes as they slept.

UN agencies say unemployment has soared to around 80% — up from nearly 50% before the war — and that almost the entire population is living in poverty. Even those with means would find it nearly impossible to import construction materials because of Israeli restrictions, ongoing fighting and the breakdown of law and order.

There are mountains of rubble, little water and no electricity

The first obstacle to any significant rebuilding is the rubble – mountains of it.

Where houses, shops and office buildings once stood, there are now giant drifts of rubble laced with human remains, hazardous substances and unexploded munitions.

The UN estimates the war has left some 40 million tons of debris and rubble in Gaza, enough to fill New York’s Central Park to a depth of eight meters (about 25 feet). It could take up to 15 years and nearly $650 million to clear it all away, it said.

There’s also the question of where to dispose of it: The UN estimates about five square kilometers (about two square miles) of land would be needed, which will be hard to come by in the small and densely populated territory.

It isn’t just homes that were destroyed, but also critical infrastructure.

The UN estimates nearly 70% of Gaza’s water and sanitation plants have been destroyed or damaged. That includes all five of the territory’s wastewater treatment facilities, plus desalination plants, sewage pumping stations, wells and reservoirs.

The employees who once managed municipal water and waste systems have been displaced, and some killed. And fuel shortages have made it difficult to keep operating facilities that are still intact.

The international charity Oxfam said it applied in December for a permit to bring in desalination units, and pipes to repair water infrastructure. It took three months for Israel to approve the shipment, but it still has not entered Gaza, Oxfam said.

The destruction of sewage networks has left streets flooded with putrid water, hastening the spread of disease.

There has been no central power in Gaza since the opening days of the war, when its sole power plant was forced to shut down for lack of fuel, and more than half of the territory's electrical grid has been destroyed, according to the World Bank.

Israeli Prime Minister Benjamin Netanyahu has said he won’t allow Hamas or even the Western-backed Palestinian Authority to govern Gaza. He has said Israel will maintain open-ended security control and delegate civilian affairs to local Palestinians. But none are known to have volunteered, and Hamas has threatened to kill anyone who aids the occupation.

Rebuilding Gaza would also require the import of massive amounts of construction supplies and heavy equipment, which Israel is unlikely to allow as long as there’s a potential for Hamas to rebuild its militant infrastructure. In any case, Gaza has only a small number of crossings with limited capacity.

The Israeli military body that coordinates civilian affairs in Gaza says it does not restrict the entry of civilian supplies and allows so-called dual-use items that could also be used for military purposes. Israel allowed some construction materials in before the war under what was known as the Gaza Reconstruction Mechanism, but it was subject to heavy restrictions and delays.

The Shelter Cluster estimates that it would take 40 years to rebuild all of Gaza’s destroyed homes under that setup.

For now, aid providers are struggling just to bring in enough basic tents because of the limited number of trucks going into Gaza and the challenges of delivering aid. Efforts to bring in more robust temporary housing are still in the early stages, and no one has even tried to bring in construction materials, according to Ely.

In September, the Shelter Cluster estimated 900,000 people were still in need of tents, bedding and other items to prepare for the region's typically cold and rainy winters.
