A Russian missile strike on the Ukrainian city of Poltava on Tuesday resulted in the deaths of at least 51 people and injured hundreds, according to officials. This attack is among the deadliest in the two-and-a-half-year conflict.
Kyiv reported that the missile struck a military training facility and a nearby hospital, but it has not been specified how many of the casualties were military personnel versus civilians.
Ukrainian President Volodymyr Zelensky pledged to hold what he referred to as "Russian scum" accountable as rescue teams worked to clear the debris.
"In the latest information available, this Russian strike has claimed 51 lives," Zelensky stated in his evening address.
"The number of injured is 271. We know that there are people under the rubble of the destroyed building. Everything is being done to save as many lives as possible," Zelensky said.
Berlin, London and Washington all condemned the strike.
US National Security Council spokesman John Kirby said the attack was "another horrific reminder of (Russian President Vladimir) Putin´s brutality", adding that the United States would send more military aid to Kyiv in the coming weeks.
British Foreign Secretary David Lammy called it a "sickening act of aggression", while German Foreign Minister Annalena Baerbock said Putin´s brutality "knows no limits".
The strike triggered anger on Ukrainian social media after unconfirmed reports said it had targeted an outdoor military ceremony, with many blaming reckless behaviour from officials who allowed the event to take place despite the threat of Russian attacks.
Zelensky said he had ordered a "full and prompt investigation into all the circumstances".
Two Russian ballistic missiles hit the hospital and educational institution, partially destroying one of the buildings, Zelensky said.
The strike took place in the morning in Poltava, a city with a pre-war population of around 300,000 people, some 300 kilometres (190 miles) east of Kyiv.
"The window blew open. Dust was everywhere. I just had time to tell my sister that a rocket was flying," said Yevgeniya Chyrva, a resident in a building damaged during the attack.
The defence ministry said that the time between the alarm and the arrival of the missiles was "so short that it caught people in the middle of evacuating to the bomb shelter".
The Poltava military communications institute, founded in the 1960s when Ukraine was part of the USSR, specialises in training telecommunications specialists.
"One of the institute´s buildings was partially destroyed, and many people were trapped under the rubble," the defence ministry said.
An AFP journalist on the scene saw several ambulances heading towards the affected site shortly after the attack on the military institute.
Rescuers were still at work after managing to save 25 people, including 11 trapped under the rubble, the defence ministry said.
Official channels and local media shared messages urging locals to donate blood to help treat the wounded.
At the same time, criticism of Ukrainian officials swirled online.
"Poltava... How can such a large number of people gather at such a facility?" said one blogger, Sergey Naumovich.
There had been some reports from Russian military bloggers that the strike targeted an outdoor ceremony.
Poltava´s governor, Philip Pronin, said his administration could not provide more details of the circumstances of the strike "for security reasons".
"The enemy is using any means to bring Ukraine more pain and disorientate Ukrainians. Please trust only reliable sources," he said.
Ukrainian MP Maria Bezugla, who regularly criticises the country´s military leadership, accused high-ranking officials of endangering soldiers by allowing such events.
"These tragedies keep repeating themselves. When will it stop?" she posted on Telegram.
The attack follows another recent scandal for Ukraine´s army command after a US-made F-16 fighter jet crashed in combat last week, killing the pilot.
The crash of the F-16 was a high-profile setback for Kyiv, which had lobbied the West to send the advanced fighter jet for months, and triggered the dismissal of the country´s air force chief, Mykola Oleshchuk.
