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.

Recent social media videos show Ukrainian forces using drones similar to IEDs. The drones sit next to roads and then strike Russian military vehicles when they pass.

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.
