 Three people were hurt by shards of broken glass on June 9, when a drone struck a residential building in the southern Russian city of Voronezh, regional governor Alexander Guzov said. Video showed damage and scorch marks to the facade of the apartment block. Guzov said the three people had received medical attention on the spot and declined hospital treatment, suggesting their injuries were light. Drone strikes inside Russian territory have become a frequent occurrence, but they more typically happen in areas such as Belgorod that lie closer to Ukraine. Voronezh is about 180 kilometers from the Ukrainian border. Ukraine does not comment on alleged cross-border attacks into Russia. Russia accused Ukraine last month of launching two drones at the Kremlin in what it said was an attempt to kill President Vladimir Putin. Kiev denied involvement in that incident.
