Russia-Ukraine war at a glance: what we know on day 610

Volodymyr Zelenskiy has said Ukraine is preparing for renewed Russian attacks on its energy infrastructure ahead of the second winter of Vladimir Putin’s full-scale invasion of the country – and that the country is ready to counterattack if targeted. “We are preparing for terrorist attacks on our energy infrastructure,” Zelenskiy said. “This year we will not only defend ourselves, but also respond.”

Russia claims it has tested its ability to deliver a retaliatory nuclear strike in an exercise involving the launch of missiles by land, sea and air. News of the exercise was delivered on Russian state TV by the defence minister, Sergei Shoigu.

The exercise followed Russia’s parliament completing the passing of a law that withdraws Moscow’s ratification of the global treaty banning nuclear weapons tests. Russia’s upper house, the Federation Council, approved the law by 156 votes to zero earlier today after the lower house, the Duma, had also passed it unanimously. Russia says it is revoking its withdrawal of the treaty only to bring itself in line with the US, which signed but never ratified the same document.

Russia’s military claimed on Wednesday that its air defence forces had shot down two long-range US-made ATACM missiles fired by Ukraine at Russian targets in what state media said was the first downing of its kind. Russia’s defence ministry reported the interception in one of its regular updates on the war in Ukraine, something Moscow still calls “a special military operation.” It did not provide further details. The Reuters news agency was unable to independently verify Moscow’s claim and there was no immediate comment from Kyiv or Washington.

A drone attack by Russia near Ukraine’s Khmelnytskyi nuclear power plant temporarily cut power to some off-site radiation monitoring stations, the International Atomic Energy Agency said. “This incident again underlines the extremely precarious nuclear safety situation in Ukraine,” said the IAEA’s director general, Rafael Mariano Grossi.

In his nightly address, Zelenskiy accused Russia of targeting the power plant. “It is most likely that the target for these drones was the Khmelnytskyi nuclear power station. The shockwave from the explosion shattered windows, including on the nuclear power station’s premises,” he said.

The attack involved 11 Shahed drones and injured 16 people according to local authorities. Power lines were also damaged, with two towns close to the nuclear power plant, Netishyn and Slavuta, facing power cuts. Ukraine’s air force said it stopped all the drones that were launched.

Russian forces are disregarding heavy losses and pressing on with a drive to capture the eastern city of Avdiivka, Ukrainian officials have claimed. “The enemy is trying to move forward and then we beat them back,” Oleksandr Shtupun, a spokesperson for Ukraine’s southern groups of forces, said on national TV. Russia has focused on the eastern Ukrainian regions of Donetsk and Luhansk since failing in its initial drive on the capital Kyiv after mounting its invasion in February 2022.

Ukraine said it was aiming to increase domestic manufacture of its own drones, producing tens of thousands every month by the end of the year. Kyiv has relied heavily on foreign-made drones in the war so far, but is looking to ramp up its output despite the challenge posed by Russia’s invasion.
