Ukrainian drones struck the Togliatti Kauchuk petrochemical plant in Russia's Samara Oblast in the morning hours of June 12, leading to a fire at the facility.

Axar.az informs, citing Kyiv Independent, photos and videos posted to social media purports to show long-range drones over the city of Tolyatti ahead of the attack.

Residents of Tolyatti have been hearing loud explosions for at least 40 minutes, with some powerful enough to rattle windows.

Soon after, a large fire was also seen at the Nizhnekamskneftekhim (NKNK) synthetic rubber plant in the city of Nizhnekamsk. Thick black smoke was seen billowing over the city following the attack.

NKNK, located in the Tatarstan Republic over 1,200 kilometers (745 miles) from the closest point to Ukraine's border, is one of the largest petrochemical enterprises in Eastern Europe. The plant has previously been the target of reported Ukrainian attacks, including as recently as May.
