Samara Region Hit Again as Ukrainian Drones Target Two Russian Chemical Plants

Drones struck an area near the Tolyattikauchuk and KuibyshevAzot chemical plants in Russia’s Samara region overnight, with footage and open-source analysis indicating a fire near the two facilities, according to Militarnyi on March 21.

Residents of Tolyatti reported multiple explosions overnight, while videos circulated online showed a fire in the industrial zone. ASTRA’s OSINT review, cited in the source material, linked the blaze to an area where the two chemical enterprises are located close to each other, though the exact facility hit was not immediately confirmed.

Ukraine’s Defense Forces struck the Afipsky oil refinery in Russia’s Krasnodar region overnight, reportedly hitting the AT-22/4 unit, a key installation at the start of the refinery’s crude processing chain, while debris also fell near the Port of Kavkaz, where Russian authorities reported damage to a technical vessel and three injured people, according to Serhii Sternenko, an advisor to Ukraine’s Minister of Defense.

Tolyattikauchuk is a petrochemical producer that manufactures synthetic rubber and other chemical components used in tires and rubber goods.

KuibyshevAzot produces nitrogen fertilizers and chemical feedstock, including caprolactam and polyamides, making both sites part of Russia’s broader industrial base.

The reported strike follows an earlier attack on KuibyshevAzot on March 11, which also triggered reports of fire at the Tolyatti chemical site.

That earlier incident was widely covered by Ukrainian and regional outlets, underscoring the repeated pressure on industrial facilities in the Samara region.

The overnight wave also appeared to reach Russia’s Samara region, where explosions and air defense activity were reported near Tolyatti as drones targeted industrial infrastructure.

ASTRA identified KuibyshevAzot as the likely objective, extending the strikes beyond the port of Kavkaz and the Afipsky refinery to a major chemical producer deeper inside Russia.

Later, Ukraine’s General Staff confirmed strikes on the Afipsky refinery and port infrastructure, describing both sites as facilities supporting the Russian military.
