Russian ballistic missiles struck a Ukrainian military institute in the city of Poltava and a nearby hospital, killing at least 41 people killed and injuring more than 180 others, Ukrainian President Volodymyr Zelensky said Tuesday.

Two ballistic missiles struck the area, the Ukrainian leader said, vowing that Russia would suffer consequences for the deadly attack.

“People were trapped under the rubble. Many people were rescued, but more than 180 were injured. Unfortunately, there are many casualties. As of now, we know that 41 people were killed. My deepest condolences to all of their relatives and loved ones,” Zelensky said in a statement posted to social media.

“The time interval between the alarm and the arrival of the deadly missiles was so short that it caught people during an evacuation to the bomb shelter,” Ukraine’s Defense Ministry said.
