A Russian strike on a nine-story residential building in Kharkiv, Ukraine, killed one child and injured 29 others, officials said Wednesday.
"Unfortunately, one child died. Doctors, despite their efforts, failed to resuscitate the boy," Oleg Sinegubov, head of the Kharkiv Regional State Administration, said in a statement on Telegram.
The multi-story residential building was targeted overnight by a Russian-guided aerial bomb, officials said.
