Ukraine launched one of its largest reported drone attacks against Russia overnight on Aug. 10, with Moscow claiming more than 450 UAVs targeted 16 regions and occupied Crimea. The strike came as Russia continued a week-long escalation of its bombardment campaign against Ukraine, unleashing hundreds of missiles, drones, and guided aerial bombs.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. In Russia’s Republic of Tatarstan, authorities said 12 people were killed and 39 injured following the drone attack on Nizhnekamsk. Tatarstan officials said the attack targeted industrial and civilian facilities. The regional government did not specify which sites were damaged but confirmed casualties and said Tatarstan head Rustam Minnikhanov had declared a day of mourning. An analysis of eyewitness photos and videos by Russian outlet Astra suggested that the drones may have targeted Nizhnekamskneftekhim (NKNKh), one of Russia’s largest petrochemical complexes. NKNKh is a key facility of the Volga cluster of Russian petrochemical giant Sibur and one of the country’s leading producers of synthetic rubber. The industrial zone in Nizhnekamsk where the complex is located also houses Tatneft’s oil refinery and the TAIF-NK oil processing complex. The area has previously been targeted in drone attacks. In June, drones struck the Tatneft refinery, while TAIF-NK was reportedly attacked in early July. NKNKh itself was targeted in March, when Russian authorities said one person was killed and 50 others were injured.
