Overnight drone and missile strikes between Russia and Ukraine killed civilians and damaged vital energy and port infrastructure on both sides on Sunday.
In Russia's Tatarstan region, Ukrainian drones hit the industrial city of Nizhnekamsk, killing two people and injuring 12 after a drone struck near a parked car. Local officials reported a fire at an enterprise in the city, which houses major oil and petrochemical plants.
Kyiv also claimed a drone strike on a major oil refinery in Slavyansk-on-Kuban in Krasnodar, which local authorities said injured three people and damaged a pipeline. Russian forces shot down 389 Ukrainian drones overnight, according to Moscow's defense ministry.
The Defense Intelligence of Ukraine (DIU) agency said its drones struck a key oil processing unit and the refinery's tank farm overnight, sparking a massive blaze visible from dozens of kilometers (miles) away.
Meanwhile, Russian strikes targeted Ukraine’s main Black Sea port hub of Odesa, injuring at least nine people in a massive overnight barrage. That followed a Saturday drone strike on an Odesa high-rise that killed two and injured 26.
Russian attacks also hit western Ukraine, igniting a petrol station near the Yahodyn-Dorohusk border crossing with Poland. Moscow continues targeting Ukraine's power grid ahead of winter, while Kyiv pursues long-range strikes against Russian oil infrastructure.
