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.

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.

Law enforcement authorities in Russia on Friday accused Ukrainian troops of killing 22 civilians in an occupied village of the Kursk region, including eight women who were allegedly raped before being executed.
