Officials say a Russian drone has blasted a hole in an apartment building in northeastern Ukraine during a nighttime attack that killed at least six people and wounded nine others.

A Russian drone struck a multi-storey apartment building in the northeastern Ukrainian city of Sumy early on Thursday, killing nine people and injuring 13, including a child, President Volodymyr Zelenskiy said.

On the night of January 30, the enemy struck one of the high-rise buildings in the city of Sumy. As a result of the drone hit, apartments were destroyed, and the number of casualties has once again increased,
