Clearing the wreckage at the shopping mall in the center of the city hit by a Russian missile on Monday is undergoing, said Vitalii Maletskyi, the mayor of Kremenchuk.
Maletskyi told Ukrainian television Wednesday: "Rescuers from three regions of Ukraine are working at the scene. They have not yet reached the epicenter of the explosion. There is still a large area to work on where the ceiling collapsed, the supporting structures collapsed."
Dmytro Lunin, head of Poltava region military administration, said clearing the wreckage would continue for two to three days.
Twenty-five people had been admitted to a hospital, he said. One person had died in hospital.
"Eighteen bodies and eight body fragments were found at the scene. Relatives are doing DNA tests now," Lunin told Ukrainian television, adding that three rescue officers had also been injured while dismantling the debris.
