The breach of the Nova Kakhovka dam is most worrying for what it says about the mind of Russian President Vladimir Putin and his generals – and their capacity for dangerous escalation.
It takes the war in an even more perilous direction.
The military impact is likely to be temporary. Armies blow dams or use them to unleash floodwaters for tactical advantage.
The Soviets and the Germans both did it in the Second World War.
But the gains generally do not hold. Water drains away, the ground dries out.
Ben Barry, a land war senior fellow at the International Institute of Strategic Studies, said: “It could set back any assault river crossing for a couple of weeks.
“Difficult to tell for how long. But only once the water subsides and the ground dries out will Ukraine have the same chance of a river crossing as it did before the flood.”
And he believes an attack across the swollen Dnipro is not out of the question even now.

“It’s not impossible to do an assault river crossing across a river that’s in full flood. It’s just more difficult,” he said.

Kherson main square ‘awash with water’
The Russians have blamed the Ukrainians for the attack, but most analysts have dismissed that as unlikely to impossible.
The Russians have a proven track record for accusing the other side of doing what they have themselves done. And the Russians have most to gain. Up to a point.
The breach benefits the Russians by reducing the length of the frontline it has to defend and allowing it to focus attention in the east, but not indefinitely.
And it has blowback for the Russians too, flooding some of the defensive positions they have dug in on the southern bank since retreating there last August.
So temporary gain, some self-harm and all the opprobrium that comes with carrying out yet another war crime.
Where is the margin in that for Vladimir Putin? It looks rash and premature. A disproportionate and irrational act.
But that may be the point.

Ukraine dam attack explained
Russian president ‘excels in scare tactics’
In war, it can pay to do the crazy thing, to look unhinged and keep your enemy guessing at your next act of madness.
Putin excels in scare tactics and knows the dam blast makes him look more dangerous.
If Russia was irresponsible enough to blow the dam and unleash such destruction for limited advantage, what will it do next, planners in Kyiv and the West will be asking.
The fear now is for the Zaporizhzhia nuclear power plant. The dam breach endangers the supply of water to its cooling systems. Could Russia now sabotage the plant to change the course of the war?
The destruction of the dam undoubtedly changes the risk calculus in handling Russia, but correctly calibrating it will need cool heads so it is not overdone.

Ukraine war: Major dam attack
Putin has, after all, indulged in nuclear sabre-rattling for much of this war.
It has weighed on the minds of Ukraine’s allies and made them more timid in arming Kyiv.
But so far analysts say his nuclear bluster is just that.

The nuclear option
There is no sign of Putin starting the lengthy process of bringing tactical warheads out of storage and deploying them.
And any disaster at Zaporizhzhia threatens Russia most.
The prevailing winds would be most likely to carry the fallout east across the Russian border.
The Russians have shown stunning disregard for the welfare of their own soldiers but a radioactive cloud over their defensive positions and logistics lines would be challenging to say the least.
What we can say for sure is this war has swung again in a more unpredictable direction and the longer it goes on, the more such lurches are likely to happen.
It was in the evening that the bombing started to intensify.
Salah Jundia, his father and brothers huddled together in their home in Shujaiyya, just east of Gaza City, trying to work out what to do.
It was too risky for them to leave at night. There were a lot of them too. Extended family living across four storeys. They decided they would wait until after dawn prayers.
The explosion tore through the building just before 5am, collapsing one storey on to the next.

Jundia says he survived because pieces of bedroom furniture fell on top of him.
Then he looked for his father and brothers.
“I found one of them calling for help. I removed the rubble covering him with my hands. Then I saw another brother covered in rubble but he was dead,” he told Sky News.
Jundia added: “My father was also dead. My other brother was also dead. We got them out and that is when I saw that the whole building had collapsed.”
Over the next few hours, they scrambled to rescue who they could.
An aunt and uncle and one of their children, Shaimaa. Uncle Imad and his son Mohammad. The bodies of Montasir and Mustaf.

Jundia says he could hear cries for help, but they were coming from deep in the rubble and were impossible to reach.
The rescue teams on site – civil defence they are called – did not have the kit to clear through three floors of 500 square metres, 30cm slabs of concrete.

In the afternoon, Jundia says Israel’s Defence Forces (IDF) told rescue teams to leave as they would be resuming their bombardment.
Jundia buried the bodies he had managed to pull out but he knew 15 of his family members, 12 of them children, were still somewhere inside the rubble, still crying for help.
He made a desperate video appeal, begging the Red Cross and Arab countries to pressure Israel to grant access to the site. It was picked up on a few social media accounts.
Israel won’t allow heavy equipment into Gaza. No diggers or bulldozers, nor the fuel or generators to run them.
They say it will fall into Hamas’s hands.
It was a major sticking point during the ceasefire and it is a major issue now as the bombardment continues, given the fact that hundreds if not thousands of civilians might survive if there were the equipment to extract them.

Civil defence trying to get to the Jundia family home over the next few days were halted because the IDF were in the vicinity. A family friend tried himself and was killed.
The footage that our camera teams have shot in Shujaiyya over the past two weeks shows how civil defence teams struggle to save those who are trapped and injured with the most rudimentary of equipment – plastering trowels, sledgehammers, ropes and small drills.
“The tight siege stops civil defence equipment from getting in,” says one.
They added: “So we are taking much longer to respond to these events. Time is a factor in getting these people out. So we call immediately for the necessary equipment to be allowed in for the civil defence to use.”
The IDF say they are investigating the circumstances around the Jundia family as a result of our enquiries.
In relation to the access of heavy equipment into Gaza, they say they work closely with international aid organisations to enable the delivery of humanitarian activities in accordance with international law.
The last contact Jundia had from beneath the rubble was a phone call from his uncle Ziad, three days after the strike.
“The line was open for 25 seconds then it went dead. We don’t know what happened. We tried to call, but there was no answer,” he says.
He and his family were displaced several times before they returned home to Shujaiyya – to Rafah in the south, then Khan Younis and Deir al-Balah.
Along the way, Jundia lost one brother and a nephew to Israeli bombs.
“We were happy and all the family came back. We went back to our house. It was damaged, but we improvised and we lived in it. We have nothing to do with the resistance. We are not interested in wars. But we have been gravely harmed,” he says.
China’s economy performed better than expected in the first quarter of the year – but it reflects a moment in time before the explosive trade war with the US, which has seen the world’s two biggest economies effectively decouple.
Economists had predicted that gross domestic product would grow by about 5.1% in January to March, compared with a year earlier. In the end, it grew 5.4%.
But these impressive figures obscure the very serious challenges China’s economy is facing in the wake of Donald Tump’s trade war – and it is almost certain growth will not remain this strong as the year goes on.
