Russian missile attacks in Dnipro kill at least 14; UK pledges to send Ukraine tanks to ‘push Russian troops back’; power outages across Ukraine

Russia carried out two mass rocket attacks on Ukraine on Saturday, devastating an apartment block in Dnipro and leaving at least 14 people dead and 64 injured, at least a dozen of them children. Rescue efforts were ongoing in the south-central city on Sunday. At least one person was also killed in a separate strike on a residential area in the nearby city of Kryvyi Rih. Ukrainian authorities said the targets were the country’s energy infrastructure.

The UK prime minister has confirmed the country will provide tanks to Ukraine to help Kyiv’s forces “push Russian troops back”. Downing Street said Rishi Sunak made the pledge during a call on Saturday morning with the Ukrainian president, Volodymyr Zelenskiy, and that Sunak offered Challenger 2 tanks and additional artillery systems as a sign of the UK’s “ambition to intensify our support to Ukraine”. Russia’s embassy in Britain said the move would only “intensify” the conflict.

Emergency power outages were enacted across 11 regions of Ukraine after Russian strikes on energy infrastructure. In a post on Telegram, grid operator Ukrenegro said the consumption limits in force across the country were exceeded in 11 regions, as a result of which “emergency shutdowns have been applied”.

Four explosions were heard in central Kyiv on Saturday morning. For the first time since Russia began regular missile and drone attacks on the capital in autumn, the air raid sirens sounded after the attack. Until now, the sirens have sounded 10-90 minutes before an attack, giving residents time to seek shelter.

Air raid alerts were also issued across the country, including in the major cities of Kherson and Lviv. Alerts were also issued for the regions of Kharkiv, Donestk, Dnipropetrovsk and about a dozen others.

Ukraine has called on its allies to give it more support after its troops suffered heavy losses in fighting at Soledar and Bakhmut in recent months. Russia said on Friday its forces had taken control of Soledar in east Ukraine, its first claim of victory in months of battlefield setbacks, while Kyiv said fierce fighting was continuing in the town. “To win this war, we need more military equipment, heavy equipment,” said Andriy Yermak, the head of Ukraine’s presidential office, Agence France-Presse reported.

Moldovan authorities said debris from a missile had been found in its territory near the border with Ukraine. They said on Saturday the find came “after Russia’s massive bombardment of Ukraine” and that it was the third time missiles from the conflict had fallen on to Moldova’s territory.

Former Russian president Dmitry Medvedev has accused the Japanese prime minister, Fumio Kishida, of shameful subservience to the US and suggested he should ritually disembowel himself. His remarks on Saturday were the latest in a long line of shocking and provocative statements from arch-hawk Medvedev, Reuters reported. Speaking later on Saturday, a day after a summit with the US president, Joe Biden, Kishida made no mention of Medvedev’s comment

UN nuclear watchdog boosting presence in Ukraine; hundreds of civilians trapped in eastern town of Soledar

The United Nations’ nuclear watchdog announced it would boost its presence in Ukraine to help prevent a nuclear accident during the conflict. The International Atomic Energy Agency (IAEA) said it would soon have a permanent presence at all five of Ukraine’s nuclear facilities. Currently, only the Russian-controlled Zaporizhzhia plant, which is near the frontline, has a permanent IAEA presence.

Ukraine has denied Russia’s claim that Putin’s forces have captured Soledar. On Friday, Russia’s defence ministry said its forces had taken full control of the salt mining town. Ukrainian officials denied the Russian claim, suggesting they were still holding on and counterattacking, with the Ukrainian military spokesperson Serhii Cherevatyi reporting “ongoing battles”.

Soledar is ‘Verdun for 21st century’ according to a top Ukraine official. Andriy Yermak, head of the office of the president of Ukraine, likened the fight for the town to the longest and bloodiest battle in the first world war.

Ukraine’s president, Volodymyr Zelenskiy, said on Thursday that Ukrainian forces defending Bakhmut and Soledar in the east would be armed with everything they need to keep Russian troops at bay in some of the bloodiest fighting of the war.

Hundreds of civilians remain trapped in Soledar, Ukraine has said. Pavlo Kyrylenko, the governor of Donetsk, told Ukrainian state TV that 559 civilians remained in Soledar, including 15 children, and could not be evacuated.

Satellite images taken by Maxar Technologies show the destruction inflicted upon Soledar. The Guardian has a series of striking images from inside the eastern Ukrainian town.

Ukraine is confident Britain will announce it plans to send about 10 Challenger 2 tanks to Kyiv shortly, a move it hopes will help Germany finally allow its Leopard 2s to be re-exported to the embattled country. A formal announcement is anticipated on Monday but Ukrainian sources indicated they understood that Britain had already decided in favour.

Germany will continue to “weigh every step carefully” and consult with its allies on further weapons deliveries to Ukraine, chancellor Olaf Scholz has said. The German leader is facing mounting pressure to approve German-made battle tanks for Kyiv. Scholz said Berlin would keep its “leading position” as one of Kyiv’s top supporters but said he had no intention of being rushed on “such serious things that have to do with peace and war, with the security of our country and of Europe”.

Ukraine’s security council chair Oleksiy Danilov tweeted about the plea for German tanks yesterday, and as the Economist’s Oliver Carroll points out – it’s not particularly subtle.

In light of today’s move from France to send light combat tanks to Ukraine, The New York Times’ Lara Jakes and Steven Erlanger have also examined the possibility that other countries in the West will also break a taboo that was seen as too provocative earlier in the conflict.

Western officials increasingly fear that Ukraine has only a narrow window to prepare to repel an anticipated Russian springtime offensive, and are moving fast to give the Ukrainians sophisticated weapons they had earlier refused to send for fear of provoking Moscow.

Over the last few weeks, one barrier after another has fallen, starting with an agreement by the United States in late December to send a Patriot air-defense system. That was followed by a German commitment last week to provide a Patriot missile battery, and in the span of hours, France, Germany and the United States each promised to send armored fighting vehicles to Ukraine’s battlefields for the first time.
