Two children were among 11 people killed when a Russian missile hit a residential building in Ukraine's northeastern city of Sumy, Ukrainian officials said, while another missile strike left the region's administrative centre without power.

“The number of those injured in a missile strike on Sumy has increased to 89 people, including 11 children,” the statement reads. As Ukrinform reported, on the evening of November 17, Russian forces struck an apartment building in Sumy with a ballistic missile.

Ukraine said on Monday that over 20 people were killed in Russian missile attacks in the cities of Odesa and Sumy.
