The State Railway Company of Ukraine announced on Friday that two Russian rockets had crashed into a railway station in Kramatorsk in eastern Ukraine.
The station is being used by the Russian military to evacuate civilians from bombed areas.
“Two rockets crashed into the Kramatorsk railway station. There have been accidents,” the Ukrainian railway said in a statement. It did not provide any other details.
According to the head of the Ukrainian Railways, three trains carrying refugees were blocked in the same area of Ukraine on Thursday following the airstrikes.
Ukrainian officials say Russian forces are reorganizing for a new offensive and are planning to seize as much territory as possible in eastern Ukraine, also known as the Donbass border with Russia.
Local authorities in some areas are urging civilians to leave when it is possible and relatively safe.
