There have been casualties in attacks on five stations in Ukraine, the Ukrainian railway company has announced on television. It concerns stations in the west and the centre of the country.
It is not known how many victims there are. It is also not immediately clear whether there have been any deaths. The attacks were carried out within an hour, the head of the state-owned company said.
Earlier in April, a train station in Kramatorsk was hit by a rocket.
About sixty were killed. More than a hundred people were injured. Ukraine said the Russian military was behind the attack, but Moscow denied it and blamed Ukraine itself.
