Russian missiles that struck a city in central Ukraine have killed at least 23 people and wounded more than 100, Ukrainian authorities said.
The country’s president called the attack “an open act of terrorism” against civilians in locations without military value.
Officials said Kalibr cruise missiles fired from a Russian submarine in the Black Sea struck civilian buildings in Vinnytsia, which is 268 kilometres (167 miles) south-west of the capital Kyiv.
Vinnytsia region governor Serhiy Borzov said Ukrainian air defences downed two of the total four missiles that were launched.
National Police Chief Ihor Klymenko said only six of the dead have been identified so far, while 39 people are still missing.
Three children where among the dead. Of the 66 people taken to hospital, five remained in a critical condition while 34 sustained severe injuries, Ukraine’s State Emergency Service said.
“There was a building of a medical organisation. When the first rocket hit it, glass fell from my windows,” Vinnytsia resident Svitlana Kubas, 74, said.
“And when the second wave came, it was so deafening that my head is still buzzing. It tore out the very outermost door, tore it right through the holes.”
Russia has not officially confirmed the strike, but Margarita Simonyan, head of the state-controlled Russian television network RT, said on her messaging app channel that military officials told her a building in Vinnytsia was targeted because it housed Ukrainian “Nazis”.
The missiles ignited a fire that expanded to engulf 50 cars in an adjacent car park.
The governor of the Vinnytsia region, Serhiy Borzov, said Ukrainian air defence systems shot down another four missiles over the area.
Ukrainian President Volodymyr Zelensky suggested the attack was deliberately aimed at civilians.
The strike happened as government officials from about 40 countries met in The Hague to discuss co-ordinating efforts to investigate and prosecute potential war crimes in Ukraine.
“Every day Russia is destroying the civilian population, killing Ukrainian children, directing missiles at civilian objects. Where there is no military (targets). What is it if not an open act of terrorism?” Mr Zelensky wrote on the Telegram messaging app.
Vinnytsia is one of Ukraine’s largest cities, with a population of 370,000.
Thousands of people from eastern Ukraine, where Russia has concentrated its offensive, have fled there since the start of the war.
Before the missiles hit Vinnytsia, the president’s office reported the deaths of five civilians and the wounding of another eight in Russian attacks over the past day.
One person was wounded when a missile damaged several buildings in the southern city of Mykolaiv early on Thursday, Ukrainian authorities said.
A missile attack on Wednesday killed at least five people in the city.
Russian forces also continued artillery and missile attacks in eastern Ukraine, primarily in Donetsk province after overtaking adjacent Luhansk.
The city of Lysychansk, the last major stronghold of Ukrainian resistance in Luhansk, fell to Russian forces at the beginning of the month.
Luhansk and Donetsk together make up the Donbas, a mostly Russian-speaking region of steel factories, mines and other industries.
Donetsk governor Pavlo Kyrylenko urged residents to evacuate as “quickly as possible”.
“We are urging civilians to leave the region, where electricity, water and gas are in short supply after the Russian shelling,” Mr Kyrylenko said in televised remarks.
“The fighting is intensifying, and people should stop risking their lives and leave the region.”
The British Ministry of Defence (MoD) said on Thursday that despite continued shelling in the Donbas region, Russian forces did not make major territorial gains in recent days.
“The ageing vehicles, weapons and Soviet-era tactics used by Russian forces do not lend themselves to quickly regaining or building momentum unless used in overwhelming mass – which Russia is currently unable to bring to bear,” the MoD said.
Both the Russian forces and Ukrainian militaries are seeking to replenish their depleted stocks of unmanned aerial vehicles to pinpoint enemy positions and guide artillery strikes.
Both sides are looking to procure jamming-resistant, advanced drones that could offer a decisive edge in battle.
Ukrainian officials say the demand for such technology is “immense” with crowdfunding efforts under way to raise the necessary cash for purchases.
