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.

People Returning to Sudan’s Capital: Khartoum is Not Habitable

Destroyed bridges, blackouts, empty water stations and looted hospitals across Sudan bear witness to the devastating impact on infrastructure from two years of war.

Authorities estimate hundreds of billions of dollars' worth of reconstruction would be needed. Yet there is little chance of that in the short-term given continued fighting and drone attacks on power stations, dams and fuel depots.

Not to mention a world becoming more averse to foreign aid where the biggest donor, the US, has slashed assistance.

The Sudanese army and Rapid Support Forces (RSF) have been battling since April 2023, with tens of thousands of people killed or injured and about 13 million uprooted in what aid groups call the world's worst humanitarian crisis.

Residents of the capital Khartoum have to endure weeks-long power outages, unclean water and overcrowded hospitals. Their airport is burnt out with shells of planes on the runway.

Most of the main buildings in downtown Khartoum are charred and once-wealthy neighborhoods are ghost towns with destroyed cars and unexploded shells dotting the streets.

"Khartoum is not habitable. The war has destroyed our life and our country and we feel homeless even though the army is back in control," said Tariq Ahmed, 56.

He returned briefly to his looted home in the capital before leaving it again, after the army recently pushed the RSF out of Khartoum.

One consequence of the infrastructure breakdown can be seen in a rapid cholera outbreak that has claimed 172 deaths out of 2,729 cases over the past week alone mainly in Khartoum.

Other parts of central and western Sudan, including the Darfur region, are similarly ravaged by fighting, while the extensive damage in Khartoum, once the center of service provision, reverberates across the country.

Sudanese authorities estimate reconstruction needs at $300 billion for Khartoum and $700 billion for the rest of Sudan.

The UN is doing its own estimates.

Sudan's oil production has more than halved to 24,000 barrels-per-day and its refining capabilities ceased as the main al-Jaili oil refinery sustained $3 billion in damages during battles, Oil and Energy Minister Mohieddine Naeem told Reuters.

Without refining capacity, Sudan now exports all its crude and relies on imports, he said. It also struggles to maintain pipelines needed by South Sudan for its own exports.

Earlier this month, drones targeted fuel depots and the airport at the country's main port city.

All of Khartoum's power stations have been destroyed, Naeem said. The national electrical company recently announced a plan to increase supply from Egypt to northern Sudan and said earlier in the year that repeated drone attacks to stations outside Khartoum were stretching its ability to keep the grid going.

LOOTED COPPER

Government forces re-took Khartoum earlier this year and as people return to houses turned upside down by looters, one distinctive feature has been deep holes drilled into walls and roads to uncover valuable copper wire.

On Sudan's Nile Street, once its busiest throughway, there is a ditch about one meter (three feet) deep and 4 km (2.5 miles) long, stripped of wiring and with traces of burning.

Khartoum's two main water stations went out of commission early in the war as RSF soldiers looted machinery and used fuel oil to power vehicles, according to Khartoum state spokesperson Altayeb Saadeddine.

Those who have remained in Khartoum resort to drinking water from the Nile or long-forgotten wells, exposing them to waterborne illnesses. But there are few hospitals equipped to treat them.

"There has been systematic sabotage by militias against hospitals, and most medical equipment has been looted and what remains has been deliberately destroyed," said Health Minister Haitham Mohamed Ibrahim, putting losses to the health system at $11 billion.

With two or three million people looking at returning to Khartoum, interventions were needed to avoid further humanitarian emergencies like the cholera outbreak, said United Nations Development Program resident representative Luca Renda.

But continued war and limited budget means a full-scale reconstruction plan is not in the works.

"What we can do ... with the capacity we have on the ground, is to look at smaller-scale infrastructure rehabilitation," he said, like solar-power water pumps, hospitals, and schools.

In that way, he said, the war may provide an opportunity for decentralizing services away from Khartoum, and pursuing greener energy sources.
