Last night, Russia launched a barrage of aerial attacks across Ukraine. Hundreds of drones and dozens of missiles were used. The Russian military also used the new Oreshnik hypersonic missile for only the second time since the invasion of Ukraine began almost four years ago. According to Russian state TV, that is. Ukrainian officials say at least four people were killed and 25 were wounded in Kyiv. The attack knocked out power and damaged at least 20 residential buildings in the capital.
