A deadly Russian rocket strike on a train station in a small town in central Ukraine killed at least 15 people and injured about 50 more on Wednesday, according to President Volodymyr Zelensky.
Zelensky told the UN Security Council that the attack took place in a small town in the central Dnipropetrovsk region that is home to only 3,500 people.
While first responders were on the scene, he warned that the casualty toll could go up.
The president's office said that an 11-year-old was killed by a separate instance of rocket fire.
Russia has denied that it targeted Ukrainian civilians.
On Wednesday, the 31st anniversary of the country's freedom from the Soviet Union, the Ukrainian government was anticipating an increase in attacks. The US urged Americans to leave the country if they could, with the State Department warning Tuesday that Russia planned to attack civilian infrastructure and government facilities in Ukraine. Some cities in the country have implemented curfews and banned public Independence Day celebrations due to safety concerns.
