Drone strike sparks fire at Azot chemical plant in Russia’s Tula region

This was confirmed by Tula region governor Dmitry Milyaev.

He said two people were injured in the attack on the plant.

"As a result of the UAV crash, a fire broke out at Azot in Novomoskovsk. The fire has been put out. No excess levels of harmful substances were detected," the governor wrote.

Social media reports said the explosions happened around 11:35 p.m. Locals reported hearing between five and eight blasts over the city.

This is the second drone strike on Azot in the past two weeks. The previous attack happened on May 24. Back then, Milyaev said emergency crews found damage to an acid tank at the site.

Andriy Kovalenko, head of Ukraine’s Center for Countering Disinformation, later confirmed the strike on Azot. He described the plant as a key part of Russia’s military-industrial system.

"This is where explosives are made, including TNT, used in artillery shells, air-dropped bombs, and missiles," Kovalenko said.

He added that after Russia launched its full-scale invasion, the plant switched to wartime operations. Azot now works closely with facilities that produce shells, drone parts, and remote mining systems.
