Ukrainian Foreign Minister Dmytro Kuleba described the latest wave of Russian missile attacks as "senseless barbarism" on Thursday.

"Senseless barbarism. These are the only words that come to mind seeing Russia launch another missile barrage at peaceful Ukrainian cities ahead of New Year," Kuleba said on Twitter, adding that there could be "no neutrality" in the face of such attacks.

The barrage of Russian missiles, one of the largest waves of attacks, hit several Ukrainian cities Thursday, damaging civilian infrastructure and knocking out power.
