The death toll from Russia’s missile strikes on a shopping mall in Ukraine has risen to 18.
Dmytro Lunin, the governor of Poltava Oblast, announced the update on Tuesday morning on Telegram after rescue and clean-up operations in Kremenchuk continued overnight.
Around 60 people were reported injured in the attack on Monday.
Ukraine’s prosecutor’s office also said more than 40 people were missing.
“The occupiers fired rockets at a shopping centre where there were more than a thousand civilians,” Ukrainian President Volodymyr Zelensky said on Telegram.
Mr Zelenskky also shared a video showing dark plumes of smoke rising from a burning building.
Local authorities said the fire was extinguished on Monday evening.
Ukraine blamed Russia for the attack, saying that X-22 air-to-surface missiles fired from Tu-22 long-range bombers had been used.
