An air strike hit a building sheltering civilians in Ukraine's embattled eastern city of Lysychansk on Thursday, killing at least four and wounding seven, local governor Serhiy Gaidai said.
"The rescue operation is still ongoing," Gaidai wrote on the Telegram app on Thursday evening.
The governor said a separate air strike on Thursday had hit a sanatorium building in Lysychansk and collapsed it, possibly causing further casualties.
