Russia launched a barrage of drones and missiles on Ukraine on Saturday, killing eight people and damaging dozens of residential buildings as well as energy infrastructure across the country, Ukrainian officials said.

At least four people died overnight as Russian drone and missile strikes continued to pound Ukraine’s towns and cities, local officials said Saturday. Meanwhile, Moscow’s troops continued their grinding advance through the country’s east.

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
