In Voronezh, Governor Alexander Gusev reported that air defenses destroyed 88 drones, though 13 people were injured and a fire broke out at the Sibur-owned Voronezhsintezkauchuk facility. Other attacks were reported at the LUKOIL-Permnefteorgsintez refinery in Perm, located over 1,000 km from the border. Ukraine stated the strikes were an exercise of its right to self-defense under Article 51 of the UN Charter to reduce Russian military potential.
