STORY: Video released by the police showed fire and smoke affecting a damaged building as officers combed the scene in the aftermath of what they said were strikes on the city, just a few miles south from Sievierodonetsk.
The location of the video was verified by nearby buildings, roads and street view on Google Maps. Reuters could not independently verify the authenticity of the video or the date it was filmed.
The Ukrainian National Police said in a statement on social media that Russian occupying forces shelled the centre of Lysychansk with artillery. The police said a humanitarian aid distribution centre, where more than 40 civilians were permanently sheltered, was burnt to the ground.
Reuters could not independently confirm the account.
Ukrainian President Volodymyr Zelenskiy said on Sunday he had traveled to Lysychansk and Soledar, two cities very close to some of the most intense fighting between his country's troops and Russian forces.
Ukraine claims to be regaining more control of Sievierodonetsk, where one of the war's biggest ground battles is taking place.
