According to the Financial Times and CNN, Oleksandr Kamyshin, the chief of the Ukrainian national railway company, said that five stations were hit by Russian missiles within an hour on Monday.

Kamyshin said casualties, which could mean deaths or injuries, have been reported.

The strikes will cause at least 16 passenger trains to be delayed.

The strikes are part of an effort to destroy the Ukrainian railway infrastructure, which has been used to evacuate civilians and transport troops and weapons across the country.

The station in Krasne is an electrical substation that provides power to overhead lines, according to officials.

In recent years, the railways have played a crucial role in moving troops and supplies across the country. The leaders of the U.K., a string of European countries, Defense Secretary Lloyd Austin and Secretary of State Anthony Blinken are just some of the people who have used trains. A missile strike on the Kramatorsk railway station in eastern Ukraine in April killed more than 50 people. Russia denied responsibility for the attack.

The trains go to war.

The death toll will rise to at least 50 after Russia strikes the train station.

Railroads have become a vital part of the war effort in Kyiv.
