Video footage of the incident went viral on the social media where bodies could be seen strewn across floor outside the station.

"Two rockets hit the Kramatorsk railway station. People have been hurt. We are clarifying the details," Alexander Kamyshin, the head of Ukraine's railway company wrote on social media as quoted by Daily Mail.

It later added: "According to operational data, more than 30 people were killed and more than 100 were wounded in the rocket attack on Kramatorsk railway station."

"The occupiers hit the Kramatorsk railway station with a Point-U, where thousands of peaceful Ukrainians were waiting to be evacuated… About 30 people died, about 100 people were injured to varying degrees," Ukraine's president Volodymyr Zelensky wrote in an Instagram after the attack.

"Police and rescuers are already on the scene. Russian non-humans do not abandon their methods. Lacking the strength and courage to stand up to us on the battlefield, they are cynically destroying the civilian population. This is an evil that has no limits. And if it is not punished, it will never stop," he added.
